CVE-2026-8720

CVE-2026-8720 affects wolfSSL’s HMAC-BLAKE2 APIs (wc_Blake2bHmacFinal, wc_Blake2sHmacFinal). When the supplied key length exceeds the BLAKE2 block size, the key-hashing branch reinitializes the running hash state and discards accumulated message data, causing the MAC to depend only on the key and...

CVE-2026-55962

TLS 1.3 post-handshake authentication PHA issue where a server could accept a client's Finished message without the client having sent a Certificate and CertificateVerify. The post-handshake-auth exemption that allows an empty/absent peer certificate was only intended for the initial handshake, b...

CVE-2026-55964

Chain intermediate CA:TRUE without keyCertSign accepted as a signing CA. Intermediate CA certificates are required to have the keyCertSign key usage when a Key Usage extension is present, but chain-supplied temporary CAs WOLFSSLTEMPCA added while building a certificate path were previously exempt...

CVE-2026-6679 DTLS 1.3 ACK serialization heap buffer overflow via integer truncation

A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer is authenticated. The buffer overflow was due to an integer truncation when computing the length of the ACK record-number list, causing an undersized buffer to be allocated and then overrun. This...

CVE-2026-6291

Bleichenbacher padding oracle in PKCS7 KTRI decryption. When decrypting PKCS7 EnvelopedData using RSA PKCS1 v1.5 key transport, wolfSSL returned distinguishable error codes depending on whether RSA padding validation failed versus whether the decrypted content was malformed. An attacker able to...

CVE-2026-55961 wolfSSL_PKCS7_verify() reports success for degenerate (certs-only) PKCS#7 with no signer

wolfSSLPKCS7verify returning success for a degenerate certs-only PKCS7 object that contains no signer. Such an object has empty signerInfos, so the underlying signed-data verification succeeds without authenticating any content. The compatibility-layer verify path now rejects the object when no...

EUVD-2026-39486

Partial-chain certificate verification may accept chains that terminate at a peer-supplied, untrusted intermediate certificate rather than a trusted anchor. An attacker could present a chain that ends at an intermediate they control and have it accepted as valid. This affects the OpenSSL...

CVE-2026-6091

Partial-chain certificate verification may accept chains that terminate at a peer-supplied, untrusted intermediate certificate rather than a trusted anchor. An attacker could present a chain that ends at an intermediate they control and have it accepted as valid. This affects the OpenSSL...

PT-2026-52605

Name of the Vulnerable Software and Affected Versions wolfSSL version 5.9.0 Description The functions wc Blake2bHmacFinal and wc Blake2sHmacFinal discard the message when the key length exceeds the block size. This occurs because the key-hashing branch reinitializes the running hash state, which...

PT-2026-52588

Name of the Vulnerable Software and Affected Versions wolfSSL versions prior to 5.9.1 Description The PKCS7 decode path fails to respect the caller-supplied output buffer size outputSz. This allows decoded content to be written beyond the boundaries of the provided buffer, leading to a buffer...

Jenkins Bitbucket Push and Pull Request Plugin unconditionally disables SSL/TLS certificate validation

Jenkins Bitbucket Push and Pull Request Plugin 3.3.8 and earlier unconditionally disables SSL/TLS certificate and hostname validation for the connections it makes to Bitbucket Server using Bearer token authentication. Because the Bearer token is transmitted in these requests, this allows attacker...

CURL-CVE-2026-9545 exposing HTTP/3 early data

In this scenario, libcurl first uses a proper HTTP/3 server for the initial transfers, and when it makes a second transfer to the same site it has been replaced by the attacker's impostor machine - without a valid certificate. When libcurl returns to the hostname the second time with a cached SSL...

CVE-2026-57289: Improper Certificate Validation

postgresql: PostgreSQL: Denial of Service via uncontrolled recursion in SSL/GSS negotiation

A flaw was found in PostgreSQL. Uncontrolled recursion during SSL Secure Sockets Layer and GSS Generic Security Service negotiation allows an attacker to achieve a sustained denial of service. This can be exploited by an attacker with access to a PostgreSQL AFUNIX socket. If SSL and GSS are both...

openssl: openssl: Information Disclosure from Uninitialized Memory via Invalid RSA Public Key

A flaw was found in openssl. Applications that use RSASVE key encapsulation, a method for securely exchanging encryption keys, may inadvertently expose sensitive data. This vulnerability arises when an application processes a malicious, invalid RSA public key provided by an attacker without prope...
