CVE-2026-54919 cpp-httplib: TLS certificate chain verification bypassed for IP-literal hosts on Mbed TLS and wolfSSL backends

cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. In affected Mbed TLS backend versions from 0.31.0 through 0.46.1 and wolfSSL backend versions from 0.33.0 through 0.46.1, when cpp-httplib is built with CPPHTTPLIBMBEDTLSSUPPORT or CPPHTTPLIBWOLFSSLSUPPORT and a...

CVE-2026-11310

X.509 trust-chain bypass in the OpenSSL compatibility certificate verifier wolfSSLX509verifycert. This affects only builds with --enable-opensslextra OPENSSLEXTRA and whose application validates certificates by calling X509verifycert with caller-supplied untrusted intermediate certificates; for...

CVE-2026-3336

This CVE affects AWS-LC: improper certificate validation in PKCS7_verify() can bypass certificate chain verification for PKCS7 objects with multiple signers (excluding the final signer). Impact is high (integrity risk) with network attack potential. AWS customers are not required to act, but appl...

CVE-2026-3336 PKCS7_verify Certificate Chain Validation Bypass in AWS-LC

Improper certificate validation in PKCS7verify in AWS-LC allows an unauthenticated user to bypass certificate chain verification when processing PKCS7 objects with multiple signers, except the final signer. Customers of AWS services do not need to take action. Applications using AWS-LC should...

Linux Distros Unpatched Vulnerability : CVE-2009-0127

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - M2Crypto does not properly check the return value from the OpenSSL EVPVerifyFinal, DSAverify, ECDSAverify, DSAdoverify, and ECDSAdoverify functions, which might...

SUSE CVE-2009-0126

The decryptpublic function in lib/crypt.cpp in the client in Berkeley Open Infrastructure for Network Computing BOINC 6.2.14 and 6.4.5 does not check the return value from the OpenSSL RSApublicdecrypt function, which allows remote attackers to bypass validation of the certificate chain via a...

SUSE CVE-2009-3046

Opera before 10.00 does not check all intermediate X.509 certificates for revocation, which makes it easier for remote SSL servers to bypass validation of the certificate chain via a revoked certificate...

The vulnerability of the OpenSSL library, which allows a hacker to bypass the standard procedures for verifying certificate chains

The vulnerability of the X509verifycert function in the OpenSSL library is related to insufficient handling of the X.509 Basic Constraints cA value during the identification of an alternative certificate chain. Exploiting this vulnerability allows a malicious actor to bypass the standard...

ntp incorrectly checks for malformed signatures

NTP 4.2.4 before 4.2.4p5 and 4.2.5 before 4.2.5p150 does not properly check the return value from the OpenSSL EVPVerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys, a similar vulnerability to...

CVE-2009-0130

lib/crypto/csrc/cryptodrv.c in erlang does not properly check the return value from the OpenSSL DSAdoverify function, which might allow remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077. NOTE: a package...
