CVE-2026-6739 Mattermost: Delegated admins could patch protected default system roles

Mattermost versions 11.6.x = 11.6.1, 11.5.x = 11.5.4, 10.11.x = 10.11.15, 10.11.x = 10.11.16 fail to require system-level permission when patching protected default system roles, which allows authenticated users with delegated user-management permissions to escalate privileges by altering built-i...

CVE-2026-9641

CVE-2026-9641 affects Crypt::PBKDF2 for Perl prior to 0.261630. The vulnerability stems from a weak default configuration: using HMAC-SHA1 as the default algorithm and a default 1000 iterations, which is insufficient for modern password hashing. The impact, per sources, could involve reduced resi...

CVE-2026-9641 Crypt::PBKDF2 versions before 0.261630 for Perl have a weak default algorithm and number of iterations

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...
