CWE-290
Authentication Bypass by Spoofing
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
CVE-2026-50141 (GCVE-0-2026-50141)
Vulnerability from cvelistv5 – Published: 2026-06-18 14:13 – Updated: 2026-06-18 16:10

Title
Woodpecker gRPC agent_id metadata can be spoofed- cross-tenant agent impersonation
Summary
Woodpecker is a CI/CD engine. Starting in version 3.0.0 and prior to version 3.14.1, a vulnerability in Woodpecker CI's gRPC layer allowed any authenticated agent to impersonate any other agent on the same server by injecting a forged `agent_id` value into outgoing gRPC metadata. The server correctly verified the JWT token but then discarded the verified agent identity in favor of the client-supplied value. Version 3.14.1 patches the issue. As a workaround, disable org agents (`WOODPECKER_DISABLE_USER_AGENT_REGISTRATION=true`) and delete existing ones.

OpenClaw < 2026.5.7 - Privilege Escalation via Mutable Display Names in Matrix allowFrom
Summary
OpenClaw before 2026.5.7 contains a privilege escalation vulnerability in the Matrix allowFrom feature that allows authenticated accounts to match policy entries through mutable display name metadata. Attackers with the ability to change display names can receive agent access intended for another Matrix identity, potentially gaining unauthorized permissions depending on operator configuration.

OpenClaw < 2026.5.22 - Control UI Locality Spoofing in Device Pairing
Summary
OpenClaw before 2026.5.22 contains a locality validation vulnerability in Control UI pairing that allows attackers with network access to spoof locality information and obtain durable admin-capable device tokens. Attackers can exploit insufficient locality-derived trust validation to convert temporary shared access into persistent administrative credentials that survive token rotation.

Title
OpenClaw < 2026.5.18 - Identity Header Forgery via Trusted-Proxy Configuration
Summary
OpenClaw before 2026.5.18 contains an identity header validation vulnerability allowing local same-host callers to forge trusted-proxy identity headers. Attackers with access to the proxy-facing Gateway port can supply forged identity headers to assume operator identity and potentially escalate privileges.

OpenClaw < 2026.5.7 - Privilege Escalation via Mutable Discord Display Names in allowFrom
Summary
OpenClaw before 2026.5.7 contains a privilege escalation vulnerability where the allowFrom feature improperly validates Discord account identity using mutable display names instead of immutable user IDs. Attackers with Discord accounts can change their display name to match a policy entry and gain unauthorized agent access intended for another Discord identity.

Title
OpenClaw < 2026.5.3 - Mutable Display Name Binding in Zalo allowFrom Policy
Summary
OpenClaw before 2026.5.3 contains a policy enforcement vulnerability where Zalo contacts with mutable display metadata could match allowFrom policy entries through display name changes. Attackers with mutable display names could receive agent responses intended for different Zalo identities when the feature is enabled.

Title
Tinyproxy - Stathost Detection Bypass via Host Header Manipulation
Summary
Tinyproxy through 1.11.3, fixed in commit 09312a1, fails to properly validate the Host header during stathost detection, allowing unauthenticated attackers to access the stats page by injecting a matching Host header or bypass detection via port manipulation. Remote attackers can trigger unauthorized access to internal proxy statistics or misroute requests as transparent proxy connections to circumvent access controls.

CAPEC-21: Exploitation of Trusted Identifiers
An adversary guesses, obtains, or "rides" a trusted identifier (e.g. session ID, resource ID, cookie, etc.) to perform authorized actions under the guise of an authenticated user or service.
CAPEC-22: Exploiting Trust in Client
An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
CAPEC-459: Creating a Rogue Certification Authority Certificate
An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
CAPEC-461: Web Services API Signature Forgery Leveraging Hash Function Extension Weakness
An adversary utilizes a hash function extension/padding weakness, to modify the parameters passed to the web service requesting authentication by generating their own call in order to generate a legitimate signature hash (as described in the notes), without knowledge of the secret token sometimes provided by the web service.
CAPEC-473: Signature Spoof
An attacker generates a message or datablock that causes the recipient to believe that the message or datablock was generated and cryptographically signed by an authoritative or reputable source, misleading a victim or victim operating system into performing malicious actions.
CAPEC-476: Signature Spoofing by Misrepresentation
An attacker exploits a weakness in the parsing or display code of the recipient software to generate a data blob containing a supposedly valid signature, but the signer's identity is falsely represented, which can lead to the attacker manipulating the recipient software or its victim user to perform compromising actions.
CAPEC-59: Session Credential Falsification through Prediction
This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
CAPEC-60: Reusing Session IDs (aka Session Replay)
This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
CAPEC-667: Bluetooth Impersonation AttackS (BIAS)
An adversary disguises the MAC address of their Bluetooth enabled device to one for which there exists an active and trusted connection and authenticates successfully. The adversary can then perform malicious actions on the target Bluetooth device depending on the target’s capabilities.
CAPEC-94: Adversary in the Middle (AiTM)
An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
