CVE-2026-86117 Sep 05, 10:16 CRITICAL Act Now

Authentication bypass in Coolify (self-hosted PaaS) through version 4.3.17 lets remote attackers take over any account by matching only on email address during the OAuth callback. Because the OauthController fails to verify provider assertions or bind an OAuth identity to the local account, an attacker who registers a victim's email on any enabled OAuth provider is signed in as that victim, defeating passwords and two-factor authentication. VulnCheck published an advisory and a third-party writeup documents the flaw; no public exploit tooling beyond the writeup and no active exploitation are confirmed at time of analysis.

CVE-2026-13447 Sep 05, 05:30 CRITICAL Act Now

Authentication bypass in the InspireUI Mstore API plugin for WordPress (versions up to and including 4.20.0) lets unauthenticated attackers forge Firebase Phone Auth JWTs and impersonate any phone number. The FirebasePhoneAuthHelper::verify_id_token() function checks token claims (alg, kid, aud, iss) but never verifies the cryptographic signature against Google's public certificates, so an attacker can sign a token with their own RSA key and log into or create arbitrary WordPress accounts. Reported by Wordfence with a CVSS of 9.8; no public exploit identified at time of analysis and the plugin is not in CISA KEV.

Unauthenticated access to the stats/login endpoint in jofpin trape 1.0.0 exposes collected tracking statistics to any remote party without credentials via the core/stats.py component. The missing authentication check (CWE-287) allows the statistics interface to be queried freely over the network, leaking data about tracked individuals - a meaningful privacy concern given trape's purpose as a people-tracking OSINT tool. A proof-of-concept exploit is publicly available, and the vendor has not responded to the GitHub issue report disclosing the flaw.

Authentication bypass in Frappe CRM prior to v1.73.0 allows network-accessible attackers to impersonate users by replaying logged invitation keys against the crm/api endpoint. The root cause is that invitation keys were never invalidated after acceptance - they remained logged and reusable indefinitely. The vendor released a patch in v1.73.0; no public exploit or CISA KEV listing has been identified at time of analysis.

Remote authenticated attackers can bypass security restrictions in IBM i 7.3 through 7.6 by exploiting improper authentication logic during service-name matching (CWE-287). The flaw allows a low-privileged authenticated user to overstep their authorized service boundaries, achieving limited unauthorized reads and writes with no user interaction required. No public exploit code exists and this CVE does not appear in the CISA KEV catalog; IBM has released a patch via the support portal.

CVE-2026-18221 Sep 04, 16:25 HIGH PATCH This Week

Authentication bypass in IBM i 7.3 through 7.6 allows remote unauthenticated attackers to gain unauthorized access by exploiting improper validation of client-supplied authentication parameters. The CVSS vector (AV:N/AC:H/PR:N/UI:N) indicates network-reachable exploitation without credentials, though elevated attack complexity (AC:H) implies specific conditions must be met. Full confidentiality, integrity, and availability impact are assigned, suggesting successful exploitation grants substantial control over the affected system. No public exploit code or CISA KEV listing has been identified at time of analysis.

CVE-2026-85596 Sep 04, 11:30 HIGH This Week

Client certificate authentication bypass in Traefik v3.7.0-v3.7.10 allows unauthenticated network clients to reach services protected by the nginx.ingress.kubernetes.io/auth-tls-verify-client: "on" annotation without presenting a valid mTLS client certificate. The flaw stems from a naming collision in the Kubernetes Ingress NGINX provider: when two Ingress objects share the same host, client CA secret, and authentication mode, Traefik's conflict-resolution logic silently falls back to the entry point's default TLS configuration, which imposes no client certificate requirement. No public exploit has been identified at time of analysis, and the issue is fixed in Traefik v3.7.11.

Authentication bypass in Traefik reverse proxy before v2.11.55 lets remote unauthenticated attackers defeat any route protected by the digestAuth middleware. The flaw stems from the middleware returning an empty secret for unknown usernames rather than rejecting them, so an attacker can craft a mathematically valid digest response from that empty secret and arbitrary credentials. Reported by VulnCheck with a fix in v2.11.55; no public exploit identified at time of analysis, though the trivial nature of the bypass makes weaponization straightforward.

Improper authentication in Adobe ColdFusion 2023 and 2025 allows unauthenticated adjacent-network attackers to escalate privileges and gain limited read and write access to affected systems. The vulnerable administrative component is network-restricted by default, which partially contains exposure, but the scope change indicator in the CVSS vector signals that successful exploitation can affect components beyond the directly targeted service.

SEPPmail Secure Email Gateway (SEG) before 15.0.7 establishes a fully privileged session prior to completing multi-factor authentication enrollment, allowing an attacker who possesses credentials for an MFA-required but not-yet-enrolled account to bypass the second factor entirely. The flaw is a session lifecycle error - the gateway incorrectly grants access rights before the enrollment ceremony is finished, collapsing MFA to single-factor authentication for affected accounts. No public exploit code or CISA KEV listing has been identified at time of analysis, though NCSC.ch has reported the issue, suggesting coordinated disclosure with the Swiss vendor.
