GHSA-PPP5-5V6C-4JWP Forge has signature forgery in RSA-PKCS due to ASN.1 extra field

Summary RSASSA PKCS1 v1.5 signature verification accepts forged signatures for low public exponent keys e=3. Attackers can forge signatures by stuffing “garbage” bytes within the ASN structure in order to construct a signature that passes verification, enabling Bleichenbacher style forgery. This...

CVE-2026-33488

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the createKeys function in the LoginControl plugin's PGP 2FA system generates 512-bit RSA keys, which have been publicly factorable since 1999. An attacker who obtains a target user's public key can factor the...

CVE-2026-33488 AVideo has a PGP 2FA Bypass via Cryptographically Broken 512-bit RSA Key Generation in LoginControl Plugin

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the createKeys function in the LoginControl plugin's PGP 2FA system generates 512-bit RSA keys, which have been publicly factorable since 1999. An attacker who obtains a target user's public key can factor the...

CVE-2026-4603

A flaw was found in jsrsasign. An attacker can exploit a division by zero vulnerability by supplying a specially crafted JSON Web Key JWK whose modulus decodes to zero. This vulnerability can force RSA public-key operations, such as verification and encryption, to produce deterministic zero...

jsrsasign: Division by Zero Allows Invalid JWK Modulus to Cause Deterministic Zero Output in RSA Operations

Versions of the package jsrsasign before 11.1.1 are vulnerable to Division by zero due to the RSASetPublic/KEYUTIL parsing path in ext/rsa.js and the BigInteger.modPowInt reduction logic in ext/jsbn.js. An attacker can force RSA public-key operations e.g., verify and encryption to collapse to...

WWBN AVideo 加密问题漏洞

WWBN AVideo is a video platform building system developed by the WWBN team using PHP. Versions of WWBN AVideo prior to 26.0 contained vulnerabilities related to encryption. These vulnerabilities stemmed from the use of weak RSA keys and the lack of authentication at the endpoint, which could lead...

curl: Function `do_pubkey()` can have out-of-bound read issue

Summary A 1-byte out-of-bounds heap read in dopubkey in lib/vtls/x509asn1.c. When parsing an RSA public key with a zero-length or all-zero modulus, the loop dereferences a pointer before checking bounds. Requires a non-OpenSSL TLS backend e.g., Mbed/Gnu. A certificate chain verification can trigg...
