Detailsinfo

A vulnerability, which was classified as problematic, was found in ARODLAND Crypt::PBKDF2 up to 0.261629 on Perl. Affected is an unknown code. The manipulation with an unknown input leads to a weak password hash vulnerability. CWE is classifying the issue as CWE-916. The product generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort that would make password cracking attacks infeasible or expensive. This is going to have an impact on confidentiality. CVE summarizes:

Crypt::PBKDF2 versions before 0.261630 for Perl have a weak default algorithm and number of iterations. The default algorithm is HMAC-SHA1, which should only be used for legacy systems. These versions default to using 1000 iterations. Depending on the chosen algorithm, 220,000 to 1,400,000 iterations should be used.

The advisory is shared for download at cheatsheetseries.owasp.org. This vulnerability is traded as CVE-2026-9641 since 05/26/2026. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1552.

Upgrading to version 0.261630 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2026-36470). Once again VulDB remains the best source for vulnerability data.
