CVE-2026-102669

The Joyland AI app is vulnerable to a security flaw because it does not verify hostnames . This improper validation of certificates with host mismatches (CWE-297) allows a malicious host to establish a connection or intercept chat messages . No specific exploit information or remediation details ...

python: python: Certificate verification bypass via missing server_hostname validation in SSLContext.wrap_bio()

A flaw was found in Python. When establishing secure connections using the SSLContext.wrapbio function with hostname checking enabled, the module fails to validate that a target server hostname is supplied. Because of this missing check, certificate hostname verification is silently skipped rathe...

PyJWT.decode() reintroduces options-dict mutation, enabling silent claim-verification bypass on dict reuse

SummaryPyJWT.decode/decodecomplete mutates a caller-supplied options dict in place whenever verifysignature is falsy, adding verifyexp/verifynbf/verifyiat/verifyaud/verifyiss/verifysub/verifyjti keys directly onto that object. If application code reuses the same options dict across calls a config...

CVE-2026-79901 Predictable Active Directory service-account passwords in BoKS Manager

In deployments using BoKS keytab management, affected versions of bokskeytabmd generate Active Directory service-account passwords from a predictable pseudo-random sequence seeded with the current Unix timestamp. An attacker who knows the service principal and can estimate the password-change tim...

BIT-PHP-MIN-2026-91769 TLS Hostname Verification Falls Back to CN After SAN Mismatch

PHP's OpenSSL stream peer verification checks the certificate's subjectAltName entries first and, whenever no entry matches, falls back to the Common Name. RFC 6125 requires the CN to be ignored once the certificate presents any service identity, so a certificate carrying a non-matching DNS SAN w...
