# CVE-2026-81181: SysReptor: Session Fixation in Password-Protected Shared Notes

- Exploited (CISA KEV): no
- Published: 2026-09-18
- CVSS: 3.7 LOW (v3.1)
- EPSS: no score
- CWE: CWE-384

SysReptor is a fully customizable pentest reporting platform. Prior to 2026.68, the password authentication flow for protected shared notes does not rotate the session identifier after successful authentication, allowing session fixation. An attacker who can obtain an unauthenticated SysReptor session cookie, place it in a victim's browser, and know the shared-note URL where the victim authenticates can reuse the fixed session after the victim enters the correct password and access that shared note. The main SysReptor login flow is not affected. This issue is fixed in version 2026.68.

"No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed. In both cases generic rules may still block it.
