Authentication bypass in Casdoor (versions ≤2.362.0) allows remote attackers to replay captured SAML assertions to hijack any user account, including administrators, without credentials or MFA. The SAML service provider implementation lacks assertion ID caching, OneTimeUse condition enforcement, and any form of replay detection, making any intercepted assertion indefinitely reusable. No public exploit identified at time of analysis, but the vulnerability was disclosed via CERT/CC (VU#780781), indicating coordinated vendor notification.
Authenticated cross-device task-result injection in Microsoft UFO's constellation architecture allows a low-privileged peer device to hijack the pending task response of a victim device by spoofing a TASK_END message. Specifically in version 3.0.1-4-ge2626659, the constellation server resolves pending Futures keyed solely on session_id without binding verification to the originating device, meaning any authenticated constellation participant who can supply a matching session_id can substitute attacker-controlled result data into the victim device's task flow. No public exploit has been identified at time of analysis and this CVE is not listed in the CISA KEV catalog, though the high-complexity CVSS vector (AC:H) reflects the session_id guessing or observation requirement.
Token replay exploitation in Red Hat Build of Keycloak's WebAuthn flow allows an unauthenticated remote attacker who intercepts an ExecuteActionsActionToken email link to enroll their own hardware-backed WebAuthn authenticator to a victim's account. Successful exploitation bypasses authentication entirely and grants the attacker persistent, credential-backed access to the compromised account. No public exploit code has been identified at time of analysis, and CISA KEV confirmation is absent, but the High confidentiality and integrity impact from CVSS underscores the severity if the attack preconditions are met.
Cross-proxy Digest authentication state leak in curl allows remote attackers to obtain sensitive authentication credentials when curl is used with proxy authentication across multiple proxy hops. The vulnerability affects curl versions from 7.12.0 through 8.19.0 due to improper handling of Digest authentication state between proxies, enabling credential disclosure with network-level access and no authentication requirements. EPSS score of 0.03% suggests low real-world exploitation probability despite the information disclosure impact.
OpenClaw before 2026.3.31 contains a replay detection bypass vulnerability in webhook signature handling that treats Base64 and Base64URL encoded signatures as distinct requests. Attackers can re-encode Telnyx webhook signatures to bypass replay detection while maintaining valid signature verification.
OpenClaw's Plivo V2 signature verification implementation allows remote attackers to bypass replay protection and forge authenticated requests by manipulating URL query parameters. The flaw affects OpenClaw versions before 2026.3.23 and stems from deriving replay protection keys from the full URL including query strings rather than the canonical base URL, enabling attackers to create new valid request signatures by modifying only query parameters on previously signed requests. With 8% EPSS percentile and high attack complexity (AC:H), this represents moderate real-world risk despite the 8.3 CVSS score. Public proof-of-concept commits demonstrate the vulnerability, though no active exploitation is confirmed.
Integrity protection bypass in OpenAirInterface v2.2.0 allows unauthenticated network attackers to downgrade 5G security context by forcing acceptance of IA0-only capability during initial UE registration, despite NIA1/NIA2 being configured. Exploitation enables replay attacks against mobile network infrastructure through manipulation of Security Mode Complete messages, compromising session integrity without confidentiality impact. No public exploit identified at time of analysis.
A logic error in the mppx npm package (versions <0.4.11) allows remote attackers to close payment channels without committing funds by exploiting an off-by-one validation flaw in the tempo/session cooperative close handler. The handler incorrectly used '<' instead of '<=' when validating close voucher amounts against settled on-chain amounts, enabling attackers to submit vouchers exactly equal to settled amounts for free channel closure or griefing attacks. No active exploitation confirmed (CISA KEV), but publicly available patch and detailed advisory increase exploitation risk. CVSS 7.5 (High) reflects network-accessible, low-complexity attack requiring no authentication.
Bootstrap setup code replay in OpenClaw before 2026.3.13 enables unauthenticated remote attackers to escalate privileges to operator.admin during device pairing. The vulnerability (CWE-294: Capture-replay) in src/infra/device-bootstrap.ts permits multiple verification attempts of valid bootstrap codes before approval, allowing escalation of pending pairing scopes. CVSS 9.3 (Critical) reflects network-accessible attack with low complexity and no user interaction required. EPSS data unavailable; no public exploit identified at time of analysis. Vendor-released patch available via GitHub commit 1803d16d.
Dovecot OTP authentication enables replay attacks when authentication cache is enabled and username alteration occurs in passdb, allowing attackers who observe an OTP exchange to authenticate as the targeted user. Open-XChange Dovecot Pro is affected (CPE: cpe:2.3:a:open-xchange_gmbh:ox_dovecot_pro:*:*:*:*:*:*:*:*). No public exploit identified at time of analysis, though the vulnerability requires relatively specific preconditions (enabled cache, username modification in passdb) to be exploitable. The CVSS 6.8 score reflects high confidentiality and integrity impact but requires high attack complexity and user interaction.
