Crypt::Sodium::XS module versions prior to 0.000042, for Perl, include a vulnerable version of libsodium
Crypt::Sodium::XS module versions prior to 0.000042, for Perl, include a vulnerable version of libsodium libsodium <= 1.0.20 or a version of libsodium released before December 30, 2025 contains a vulnerability documented as CVE-2025-69277  https://www.cve.org/CVERecord?id=CVE-2025-69277 . The libsodium vulnerability states: In atypical use cases involving certain custom cryptography or untrusted data to crypto_core_ed25519_is_valid_point, mishandles checks for whether an elliptic curve point is valid because it sometimes allows points that aren't in the main cryptographic group. 0.000042 includes a version of libsodium updated to 1.0.20-stable, released January 3, 2026, which includes a fix for the vulnerability.
CVE-2025-68972 Média · 4.7 CWE-347 27/12/2025
Improper Verification of Cryptographic Signature em Gnupg
In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can construct a modified message that places additional text after the signed material, such that signature verification of the modified message succeeds (although an "invalid armor" message is printed during verification). This is related to use of \f as a marker to denote truncation of a long plaintext line.

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.
CVE-2025-55311 Média · 6.5 CWE-347 11/12/2025

An issue was discovered in Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2. A crafted PDF can use JavaScript to alter annotation content and subsequently clear the file's modification status via JavaScript interfaces. This circumvents digital signature verification by hiding document modifications, allowing an attacker to mislead users about the document's integrity and compromise the trustworthiness of signed PDFs.

CVE-2025-66568 Crítica · 9.1 CWE-347 09/12/2025
ruby-saml Libxml2 Canonicalization errors can bypass Digest/Signature validation
The ruby-saml library implements the client side of an SAML authorization. Versions up to and including 1.12.4, are vulnerable to authentication bypass through the libxml2 canonicalization process used by Nokogiri for document transformation, which allows an attacker to execute a Signature Wrapping attack. When libxml2’s canonicalization is invoked on an invalid XML input, it may return an empty string rather than a canonicalized node. ruby-saml then proceeds to compute the DigestValue over this empty string, treating it as if canonicalization succeeded. This issue is fixed in version 1.18.0.
CVE-2025-66567 Crítica · 9.1 CWE-347 09/12/2025
ruby-saml has a SAML authentication bypass due to namespace handling (parser differential)
The ruby-saml library is for implementing the client side of a SAML authorization. ruby-saml versions up to and including 1.12.4 contain an authentication bypass vulnerability due to an incomplete fix for CVE-2025-25292. ReXML and Nokogiri parse XML differently, generating entirely different document structures from the same input. This allows an attacker to execute a Signature Wrapping attack. This issue is fixed in version 1.18.0.
CVE-2025-13662 Alta · 7.8 CWE-347 09/12/2025
Improper Verification of Cryptographic Signature em Ivanti Endpoint Manager
Improper verification of cryptographic signatures in the patch management component of Ivanti Endpoint Manager prior to version 2024 SU4 SR1 allows a remote unauthenticated attacker to execute arbitrary code. User Interaction is required.
CVE-2025-65945 Alta · 7.5 CWE-347 04/12/2025
auth0/node-jws improper HMAC signature verification vulnerability
auth0/node-jws is a JSON Web Signature implementation for Node.js. In versions 3.2.2 and earlier and version 4.0.0, auth0/node-jws has an improper signature verification vulnerability when using the HS256 algorithm under specific conditions. Applications are affected when they use the jws.createVerify() function for HMAC algorithms and use user-provided data from the JSON Web Signature protected header or payload in HMAC secret lookup routines, which can allow attackers to bypass signature verification. This issue has been patched in versions 3.2.3 and 4.0.1.
CVE-2025-40934 Crítica · 9.3 CWE-347 26/11/2025
XML-Sig prior to 0.68 for Perl improperly validates XML without signatures
XML-Sig versions 0.27 through 0.67 for Perl incorrectly validates XML files if signatures are omitted. An attacker can remove the signature from the XML document to make it pass the verification check. XML-Sig is a Perl module to validate signatures on XML files.  An unsigned XML file should return an error message.  The affected versions return true when attempting to validate an XML file that contains no signatures.
CVE-2025-34324 Alta · 7.8 CWE-347 18/11/2025
GoSign Desktop < 2.4.1 Insecure Update Mechanism RCE
GoSign Desktop versions 2.4.0 and earlier use an unsigned update manifest for distributing application updates. The manifest contains package URLs and SHA-256 hashes but is not digitally signed, so its authenticity relies solely on the underlying TLS channel. In affected versions, TLS certificate validation can be disabled when a proxy is configured, allowing an attacker who can intercept network traffic to supply a malicious update manifest and corresponding package with a matching hash. This can cause the client to download and install a tampered update, resulting in arbitrary code execution with the privileges of the GoSign Desktop user on Windows and macOS, or with elevated privileges on some Linux deployments. A local attacker who can modify proxy settings may also abuse this behavior to escalate privileges by forcing installation of a crafted update.

Zoom Workplace VDI Client for Windows - Improper Verification of Cryptographic Signature
Improper verification of cryptographic signature in the installer for Zoom Workplace VDI Client for Windows may allow an authenticated user to conduct an escalation of privilege via local access.
CVE-2025-64186 Média · 6.5 CWE-347 12/11/2025
Evervault Go SDK: Incomplete PCR Validation in Enclave Attestation for non-Evervault hosted Enclaves
Evervault is a payment security solution. A vulnerability was identified in the `evervault-go` SDK’s attestation verification logic in versions of `evervault-go` prior to 1.3.2 that may allow incomplete documents to pass validation. This may cause the client to trust an enclave operator that does not meet expected integrity guarantees. The exploitability of this issue is limited in Evervault-hosted environments as an attacker would require the pre-requisite ability to serve requests from specific evervault domain names, following from our ACME challenge based TLS certificate acquisition pipeline. The vulnerability primarily affects applications which only check PCR8. Though the efficacy is also reduced for applications that check all PCR values, the impact is largely remediated by checking PCR 0, 1 and 2. The identified issue has been addressed in version 1.3.2 by validating attestation documents before storing in the cache, and replacing the naive equality checks with a new SatisfiedBy check. Those who useevervault-go to attest Enclaves that are hosted outside of Evervault environments and cannot upgrade have two possible workarounds available. Modify the application logic to fail verification if PCR8 is not explicitly present and non-empty and/or add custom pre-validation to reject documents that omit any required PCRs.

CVE-2025-55278 Alta · 8.1 CWE-347 05/11/2025
HCL DevOps Loop is susceptible to an improper authentication vulnerability
Improper authentication in the API authentication middleware of HCL DevOps Loop allows authentication tokens to be accepted without proper validation of their expiration and cryptographic signature. As a result, an attacker could potentially use expired or tampered tokens to gain unauthorized access to sensitive resources and perform actions with elevated privileges.
