CVE-2026-72861

In Appwrite templates' github-issue-bot, verifyWebhook uses an inverted condition (typeof signature !== 'string' || (await verify(...))) that short-circuits to success when the X-Hub-Signature-256 header is absent, skipping HMAC verification. Unauthenticated callers can then post arbitrary commen...

Pipelines-as-Code GitHub App token request can be redirected via untrusted Enterprise Host header

Impact Pipelines-as-Code installations using the GitHub App provider are vulnerable to GitHub App credential exfiltration through the webhook endpoint. Affected versions accepted the X-GitHub-Enterprise-Host request header as the GitHub Enterprise API host during GitHub App token generation. For...

CVE-2026-73251

Mongoose is an embedded web server and network library. Prior to 7.23, a network attacker can impersonate a TLS server to a Mongoose client configured with a multi-certificate CA bundle. In src/tlsbuiltin.c, the mgtlsinit function stores the bundle in tls-cabundleder while tls-cader.len remains...

CVE-2026-73251

Mongoose (embedded web server and network library) prior to 7.23 contains a critical TLS certificate verification flaw in src/tls_builtin.c. When a client is configured with a multi-certificate CA bundle, mg_tls_init() stores the bundle in tls->ca_bundle_der while tls->ca_der.len remains ze...

CVE-2026-73251 Mongoose Built-in TLS: CA-bundle certificate chain accepted without any signature verification

Mongoose is an embedded web server and network library. Prior to 7.23, a network attacker can impersonate a TLS server to a Mongoose client configured with a multi-certificate CA bundle. In src/tlsbuiltin.c, the mgtlsinit function stores the bundle in tls-cabundleder while tls-cader.len remains...

Azure Data Factory Elevation of Privilege Vulnerability

Improper verification of cryptographic signature in Azure Data Factory allows an unauthorized attacker to elevate privileges over a network...

PT-2026-79219

tor before 0.4.9.9 was prone to an out-of-bounds write when parsing a consensus or detached signature with unexpected signature digest type. Impact is minor for most Tor roles, but potentially major for directory authorities. This is TROVE-2026-019...

JetBrains YouTrack < 2025.3.156085 / 2026.1.x < 2026.1.13913 / 2026.2.x < 2026.2.18112 Authentication Bypass (CVE-2026-75045)

The version of JetBrains YouTrack installed on the remote host is prior to 2025.3.156085, 2026.1.x prior to 2026.1.13913, or 2026.2.x prior to 2026.2.18112. It is, therefore, affected by an authentication bypass vulnerability: - An unauthenticated attacker could download database backups via shar...

Improper cryptographic signature verification in jstfunctions.c in RDK-B WebUI rdkb-2025q4-kirkstone.04.10.26 allows a remote attacker to bypass authentication and obtain administrative access via a forged JWT containing an invalid RSA signature...

CVE-2026-19505

A flaw in jst_functions.c of RDK-B WebUI (rdkb-2025q4-kirkstone.04.10.26) fails to properly verify JWT RSA signatures, allowing a remote attacker to submit a forged token and gain administrative access. No patch version or exploit details are provided in the available documents.

CVE-2026-54330

A flaw was found in Ceph RGW's SigV4 signature verification handler. When processing S3 requests, RGW verifies only the headers explicitly listed in the X-Amz-SignedHeaders field but does not reject requests that carry additional unsigned x-amz- headers. This diverges from the AWS S3 specificatio...

CVE-2026-49283

The SimpleSAMLphp SAML2 library is a PHP library for SAML2 related functionality. Prior to versions 4.19.3, 4.20.2, 5.0.6, and 6.2.1, the HTTPArtifact::receive flow can treat an unsigned embedded SAML Response as cryptographically valid for the wrong identity provider. SOAPClient::addSSLValidator...
