CVE-2026-3255

HTTP::Session2 versions before 1.12 for Perl for Perl may generate weak session ids using the rand function. The HTTP::Session2 session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epo...

CVE-2018-25160

HTTP::Session2 versions through 1.09 for Perl does not validate the format of user provided session ids, enabling code injection or other impact depending on session backend. For example, if an application uses memcached for session storage, then it may be possible for a remote attacker to inject...

CVE-2026-2597 Crypt::SysRandom::XS versions before 0.010 for Perl is vulnerable to a heap buffer overflow in the XS function random_bytes()

Crypt::SysRandom::XS versions before 0.010 for Perl is vulnerable to a heap buffer overflow in the XS function randombytes. The function does not validate that the length parameter is non-negative. If a negative value e.g. -1 is supplied, the expression length + 1u causes an integer wraparound,...

CVE-2026-2588 Crypt::NaCl::Sodium versions through 2.001 for Perl has an integer overflow flaw on 32-bit systems

Crypt::NaCl::Sodium versions through 2.001 for Perl has an integer overflow flaw on 32-bit systems. Sodium.xs casts a STRLEN sizet to unsigned long long when passing a length pointer to libsodium functions. On 32-bit systems sizet is typically 32-bits while an unsigned long long is at least 64-bi...

CVE-2026-2588

Crypt::NaCl::Sodium for Perl has an integer overflow in 32‑bit environments, affecting versions up to 2.001. The Sodium.xs code casts a STRLEN (size_t) to unsigned long long when passing a length pointer to libsodium, creating an overflow risk where 32‑bit size_t is 32‑bit but unsigned long long ...
