php-phpseclib - implementations of an arbitrary-precision integer arithmetic library
It was discovered that phpseclib did not perform constant-time padding validation when using AES in CBC mode. A remote attacker could possibly use this issue to obtain sensitive information. ( CVE-2026-32935 ) It was discovered that phpseclib did not use a constant-time comparison when validating SSH packet authentication codes. A remote attacker could possibly use this issue to obtain sensitive information. ( CVE-2026-40194 ) It was discovered that phpseclib did not properly limit object identifier lengths when parsing ASN.1 data. An attacker could possibly use this issue to cause phpseclib to use excessive resources, leading to a denial of service. ( CVE-2026-44167 )
