CVE-2025-68972 2026-01-02 N/A 5.9 MEDIUM
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.
CVE-2025-34324 1 Infocert 1 Gosign 2025-12-31 N/A 7.8 HIGH
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.
CVE-2025-55311 3 Apple, Foxit, Microsoft 4 Macos, Pdf Editor, Pdf Reader and 1 more 2025-12-31 N/A 6.5 MEDIUM
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-2025-40934 1 Xml\ 1 \ 2025-12-30 N/A 9.3 CRITICAL
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-2023-53951 2025-12-23 N/A 9.8 CRITICAL
Ever Gauzy v0.281.9 contains a JWT authentication vulnerability that allows attackers to exploit weak HMAC secret key implementation. Attackers can leverage the exposed JWT token to authenticate and gain unauthorized access with administrative permissions.

CVE-2025-68113 2025-12-16 N/A 6.5 MEDIUM
ALTCHA is privacy-first software for captcha and bot protection. A cryptographic semantic binding flaw in ALTCHA libraries allows challenge payload splicing, which may enable replay attacks. The HMAC signature does not unambiguously bind challenge parameters to the nonce, allowing an attacker to reinterpret a valid proof-of-work submission with a modified expiration value. This may allow previously solved challenges to be reused beyond their intended lifetime, depending on server-side replay handling and deployment assumptions. The vulnerability primarily impacts abuse-prevention mechanisms such as rate limiting and bot mitigation. It does not directly affect data confidentiality or integrity. This issue has been addressed by enforcing explicit semantic separation between challenge parameters and the nonce during HMAC computation. Users are advised to upgrade to patched versions, which include version 1.0.0 of the altcha Golang package, version 1.0.0 of the altcha Rubygem, version 1.0.0 of the altcha pip package, version 1.0.0 of the altcha Erlang package, version 1.4.1 of the altcha-lib npm package, version 1.3.1 of the altcha-org/altcha Composer package, and version 1.3.0 of the org.altcha:altcha Maven package. As a mitigation, implementations may append a delimiter to the end of the `salt` value prior to HMAC computation (for example, `<salt>?expires=<time>&`). This prevents ambiguity between parameters and the nonce and is backward-compatible with existing implementations, as the delimiter is treated as a standard URL parameter separator.
CVE-2025-59803 3 Apple, Foxit, Microsoft 4 Macos, Pdf Editor, Pdf Reader and 1 more 2025-12-15 N/A 5.3 MEDIUM
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-2025-54369 2025-12-15 N/A N/A
Node-SAML is a SAML library not dependent on any frameworks that runs in Node. In versions 5.0.1 and below, Node-SAML loads the assertion from the (unsigned) original response document. This is different than the parts that are verified when checking signature. This allows an attacker to modify authentication details within a valid SAML assertion. For example, in one attack it is possible to remove any character from the SAML assertion username. This issue is fixed in version 5.1.0.

An attacker could leverage this vulnerability to bypass cryptographic protections and gain limited unauthorized write access. Exploitation of this issue does not require user interaction.
CVE-2025-13662 1 Ivanti 1 Endpoint Manager 2025-12-11 N/A 7.8 HIGH
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-2025-66567 1 Onelogin 1 Ruby-saml 2025-12-10 N/A 9.1 CRITICAL
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-2025-66568 1 Onelogin 1 Ruby-saml 2025-12-10 N/A 9.1 CRITICAL
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-2025-59719 1 Fortinet 1 Fortiweb 2025-12-09 N/A 9.8 CRITICAL
An improper verification of cryptographic signature vulnerability in Fortinet FortiWeb 8.0.0, FortiWeb 7.6.0 through 7.6.4, FortiWeb 7.4.0 through 7.4.9 may allow an unauthenticated attacker to bypass the FortiCloud SSO login authentication via a crafted SAML response message.
