CVE-2026-68511

Paaster: TOCTOU race condition defeats the 'burn after reading' guarantee on view-once pastes

Paaster is a pastebin application. Prior to version 3.3.0, Paaster's "view once" (burn-after-reading) paste mode can be bypassed with concurrent requests. The check that's supposed to enforce single-use is a plain read followed by a separate write, with no atomicity, so multiple simultaneous requests can all see the paste as "not yet read" and all successfully retrieve it. This issue has been patched in version 3.3.0.

CVE-2026-68512

Paaster: No rate limiting on account login, combined with a public username-enumeration/salt endpoint, enables offline credential-stuffing

Paaster is a pastebin application. Prior to version 3.3.0, Paaster's account login has no rate limiting, lockout, or CAPTCHA of any kind, and a companion endpoint openly discloses whether a username exists along with that account's password-hashing salts. Together these let an attacker enumerate real accounts and then brute-force their passwords with unlimited, unthrottled attempts. This issue has been patched in version 3.3.0.
