The vulnerability exists because `dologin\\s::rrand()` seeds the Mersenne Twister with `mt_srand((double) microtime() * 1000000)` — discarding the integer-seconds component of `microtime()` and constraining the seed to a range of approximately 10^6 values (~20 bits of entropy) — after which every character of the 32-character magic-link token is drawn sequentially with `mt_rand()`, making the entire token a deterministic function of that seed. Because `Pswdless::try_login()` is registered on the unauthenticated `init` hook, resolves the target account by the auto-increment numeric ID embedded in the `?dologin=<id>.<hash>` parameter, performs the hash comparison using a non-constant-time `!=` operator, and then calls `wp_set_auth_cookie()` directly — never passing through `wp_authenticate()` and therefore never triggering the plugin's own `Auth::_has_login_err()` lockout — an unauthenticated attacker can brute-force the ~10^6-candidate seed space to reconstruct an active passwordless login token and authenticate as any targeted user, including administrators, without a password. Exploitation requires that a valid, unexpired passwordless login link (active for up to 7 days) exists for the target account at the time of the attack, and that the numeric link ID is known or guessable from the auto-increment primary key."}],"title":"DoLogin Security <= 4.3 - Unauthenticated Authentication Bypass via Insufficient Randomness via 'dologin' Parameter Weak PRNG Token","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/16bce371-b524-48eb-8537-3f9df802abd3?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/dologin/tags/4.3/src/pswdless.cls.php#L86"},{"url":"https://plugins.trac.wordpress.org/browser/dologin/tags/4.3/src/s.cls.php#L240"},{"url":"https://plugins.trac.wordpress.org/browser/dologin/tags/4.3/src/pswdless.cls.php#L197"},{"url":"https://plugins.trac.wordpress.org/browser/dologin/tags/4.3/src/pswdless.cls.php#L27"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-338 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)","cweId":"CWE-338","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"samuel pages chartier"}],"timeline":[{"time":"2026-07-07T16:39:40.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-08T12:43:37.967188Z","id":"CVE-2026-14495","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-08T12:44:30.272Z"}}]}}
