CVE-2021-25981
Last modified
CVE-2021-25981 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. In Talkyard, regular versions v0.2021.20 through v0.2021.33 and dev versions v0.2021.20 through v0.2021.34, are vulnerable to Insufficient Session Expiration. This may allow an attacker to reuse the admin’s still-valid session token even when logged-out, to gain admin privileges, given the attacker is able to obtain that token (via other, hypothetical attacks). EPSS estimates a 2.46% chance of exploitation in the next 30 days.
