Vulnerability from github – Published: 2026-03-03 12:31 – Updated: 2026-03-03 12:31
VLAI
Details

A vulnerability was found in Dataease SQLBot up to 1.5.1. This impacts the function validateEmbedded of the file backend/apps/system/middleware/auth.py of the component JWT Token Handler. Performing a manipulation results in improper verification of cryptographic signature. The attack can be initiated remotely. The attack is considered to have high complexity. The exploitability is said to be difficult. The exploit has been made public and could be used. A comment in the source code warns users about using this feature. The vendor was contacted early about this disclosure.

GHSA-4XR6-9WFX-7QVW

Vulnerability from github – Published: 2025-12-11 18:30 – Updated: 2025-12-11 18:30
VLAI
Details

Foxit PDF Editor and Reader before 2025.2.1 allow signature spoofing via triggers. An attacker can embed triggers (e.g., JavaScript) in a PDF document that execute during the signing process. When a signer reviews the document, the content appears normal. However, once the signature is applied, the triggers modify content on other pages or optional content layers without explicit warning. This can cause the signed PDF to differ from what the signer saw, undermining the trustworthiness of the digital signature. The fixed versions are 2025.2.1, 14.0.1, and 13.2.1.

Summary
Duplicate Advisory: Keycloak SAML signature validation flaw
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-xgfv-xpx8-qhcr. This link is maintained to preserve external references.

Original Description

A flaw exists in the SAML signature validation method within the Keycloak XMLSignatureUtil class. The method incorrectly determines whether a SAML signature is for the full document or only for specific assertions based on the position of the signature in the XML document, rather than the Reference element used to specify the signed element. This flaw allows attackers to create crafted responses that can bypass the validation, potentially leading to privilege escalation or impersonation attacks.

GHSA-52V5-JR5W-GJXR

Vulnerability from github – Published: 2026-07-01 19:58 – Updated: 2026-07-01 19:58
VLAI
Summary
sigstore's `certificateOIDs` verification constraints are silently dropped and never enforced
Details

Summary

The documented certificateOIDs option in sigstore.verify() is accepted by the public API but discarded before verification, so required certificate extension OIDs are never checked.

Details

The public verify options include certificateOIDs and the documentation says those OID/value pairs “must be present in the certificate’s extension list.” The policy-construction path used by sigstore.verify() and createVerifier() only copies the SAN and issuer settings into the verification policy and completely ignores certificateOIDs.

As a result, callers can believe they are constraining verification to certificates carrying specific Fulcio or workload-identifying OIDs, while the actual verifier never receives those constraints. Any bundle that satisfies the remaining checks is accepted even if the required OID extensions are absent or mismatched.

This is reachable from supported usage through the documented certificateOIDs verify option.

PoC

const { createVerificationPolicy } = require("sigstore/dist/config");

const policy = createVerificationPolicy({
  certificateIssuer: "https://issuer.example",
  certificateIdentityEmail: "victim@example.com",
  certificateOIDs: {
    "1.2.3.4": "required-value",
  },
});

console.log("certificateOIDs" in policy, JSON.stringify(policy));
// false {"subjectAlternativeName":"victim@example.com","extensions":{"issuer":"https://issuer.example"}}

Impact

Applications that rely on certificateOIDs to restrict which certificates may sign artifacts receive no such protection. Unauthorized certificates that should be rejected on extension policy can be accepted as long as they satisfy the remaining verification checks.

CAPEC-463: Padding Oracle Crypto Attack

An adversary is able to efficiently decrypt data without knowing the decryption key if a target system leaks data on whether or not a padding error happened while decrypting the ciphertext. A target system that leaks this type of information becomes the padding oracle and an adversary is able to make use of that oracle to efficiently decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). In addition to performing decryption, an adversary is also able to produce valid ciphertexts (i.e., perform encryption) by using the padding oracle, all without knowing the encryption key.

CAPEC-475: Signature Spoofing by Improper Validation

An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
