CVE-2026-5083
MediumCVSS 5.3Exploitation Probability (EPSS)
Low risk35th percentile - higher than 35% of all known CVEs
Summary
In the Ado::Sessions library for Perl up to version 0.935, insecure session IDs are generated. The IDs are based on the rand() function, epoch time, and PID, making them predictable. Ado is no longer maintained and has been removed from the CPAN index.
Risk Assessment
The organization is at risk of session prediction attacks, which could allow unauthorized access to systems using Ado::Sessions.
Recommendation
Immediately replace the Ado::Sessions library with a more secure alternative, as it is no longer maintained.

Original NVD description (English source)
Ado::Sessions versions through 0.935 for Perl generates insecure session ids. The session id is generated from 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 epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. Predicable session ids could allow an attacker to gain access to systems. Note that Ado is no longer maintained, and has been removed from the CPAN index. It is still available on BackPAN.
