Detailsinfo

A vulnerability was found in CallBackery up to 0.61.x. It has been classified as critical. This affects the function cookieConf. The manipulation of the argument X-Session-Cookie/xsc with an unknown input leads to a session expiration vulnerability. CWE is classifying the issue as CWE-613. According to WASC, "Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization." This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

CallBackery versions before 0.62.0 for Perl accept session cookies of any age sent in the X-Session-Cookie header. cookieConf() rejects a cookie older than 300 seconds only when it arrives in the xsc query parameter. The same cookie sent in the X-Session-Cookie header is accepted however old it is. A session cookie that leaks through a log, a Referer header or browser history authenticates as its user indefinitely.

The advisory is shared at metacpan.org. This vulnerability is uniquely identified as CVE-2026-118987 since 10/29/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.
