CVE-2026-72861

The github-issue-bot templates in appwrite/templates verify the GitHub webhook signature with an inverted condition. verifyWebhook in node/github-issue-bot/src/github.js and in node-typescript/github-issue-bot/src/github.ts returns "typeof signature !== 'string' || await verify...", so when the...

bouncycastle: BC-JAVA: PKIX draft CompositeVerifier accepts empty signature sequence as valid

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft CompositeVerifier implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially...

CVE-2026-18568

XML::Sig versions from 0.29 before 0.72 for Perl allow signature verification bypass because verify returns true when every signature was skipped before any cryptographic check. verify in lib/XML/Sig.pm counts the //dsig:Signature elements into $numsigs and iterates over them, but two paths reach...

CVE-2026-18568

XML::Sig for Perl versions prior to 0.72 is vulnerable: verify() can return true without performing any digest or signature checks when multiple signatures are present or id_attr mismatch occurs, effectively bypassing signature verification. Affected range includes 0.29–0.71 (up to 0.28 is not af...

EUVD-2026-51914

Improper Verification of Cryptographic Signature in ueberauth guardian allows an unauthenticated attacker to revoke a victim's session with a forged token. Guardian.revoke/3 in lib/guardian.ex decodes the supplied token with peek/1, which performs no signature verification it only base64-decodes...

CVE-2026-59247 Insufficient verification of Hex package metadata in Gleam

Insufficient Verification of Data Authenticity vulnerability in Gleam allows an adversary in the middle to substitute forged Hex package contents during dependency resolution. During dependency resolution Gleam fetches package metadata from the signature-verified Hex repository, which covers each...

EUVD-2026-48509

The Payment Plugins for Stripe WooCommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.0.7. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers ...

CVE-2026-64623 Network-AI before 5.13.4 Cryptographic Signature Verification Bypass

Network-AI before 5.13.4 contains an improper cryptographic signature verification vulnerability in APSAdapter where the default local verifier accepts any non-empty string as valid. Unauthenticated attackers can submit forged APS delegation payloads with arbitrary scopes to bypass signature...

Summary Apollo ConfigService may allow unauthorized access to configuration data when AccessKey / management key authentication is enabled and ConfigService accepts a non-canonical appId variant during authentication while downstream request handling resolves it to the protected app. Details...

CVE-2026-13165

SzafirHost is affected by a remote code execution vulnerability (CVE-2026-13165) in the way it validates versus extracts native libraries from archives. The application verifies the downloaded native library archive using JarFile (Central Directory) but extracts libraries with JarInputStream (seq...

PYSEC-2026-287 Authlib JWS JWK Header Injection: Signature Verification Bypass

Description Summary A JWK Header Injection vulnerability in authlib's JWS implementation allows an unauthenticated attacker to forge arbitrary JWT tokens that pass signature verification. When key=None is passed to any JWS deserialization function, the library extracts and uses the cryptographic...

CVE-2026-11800 Org.keycloak:keycloak-services: keycloak: authentication bypass via jwt algorithm confusion

A flaw was found in Keycloak. This JWT algorithm confusion vulnerability in the JWT Authorization Grant flow allows an attacker with valid client credentials to bypass signature verification. By forging an assertion, the attacker can create unauthorized access tokens. This enables the attacker to...
