CVE-2025-55229 1 Microsoft 5 Windows, Windows 10, Windows 11 and 2 more 2025-09-17 5.3 Medium
Improper verification of cryptographic signature in Windows Certificates allows an unauthorized attacker to perform spoofing over a network.
CVE-2025-59334 2025-09-17 9.7 Critical
Linkr is a lightweight file delivery system that downloads files from a webserver. Linkr versions through 2.0.0 do not verify the integrity or authenticity of .linkr manifest files before using their contents, allowing a tampered manifest to inject arbitrary file entries into a package distribution. An attacker can modify a generated .linkr manifest (for example by adding a new entry with a malicious URL) and when a user runs the extract command the client downloads the attacker-supplied file without verification. This enables arbitrary file injection and creates a potential path to remote code execution if a downloaded malicious binary or script is later executed. Version 2.0.1 adds a manifest integrity check that compares the checksum of the original author-created manifest to the one being extracted and aborts on mismatch, warning if no original manifest is hosted. Users should update to 2.0.1 or later. As a workaround prior to updating, use only trusted .linkr manifests, manually verify manifest integrity, and host manifests on trusted servers.
CVE-2024-7344 7 Cs-grp, Greenware, Howyar and 4 more 7 Neo Impact, Greenguard, Sysreturn and 4 more 2025-09-15 8.2 High
Howyar UEFI Application "Reloader" (32-bit and 64-bit) is vulnerable to execution of unsigned software in a hardcoded path.
CVE-2024-8698 1 Redhat 4 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On and 1 more 2025-09-12 7.7 High
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.
CVE-2025-25292 3 Netapp, Omniauth, Onelogin 3 Storagegrid, Omniauth Saml, Ruby-saml 2025-09-12 9.8 Critical
ruby-saml provides security assertion markup language (SAML) single sign-on (SSO) for Ruby. An authentication bypass vulnerability was found in ruby-saml prior to versions 1.12.4 and 1.18.0 due to a parser differential. ReXML and Nokogiri parse XML differently, the parsers can generate entirely different document structures from the same XML input. That allows an attacker to be able to execute a Signature Wrapping attack. This issue may lead to authentication bypass. Versions 1.12.4 and 1.18.0 contain a patch for the issue.
CVE-2025-25291 3 Netapp, Omniauth, Onelogin 3 Storagegrid, Omniauth Saml, Ruby-saml 2025-09-12 9.8 Critical

CVE-2025-57801 1 Consensys 1 Gnark 2025-09-12 9.1 Critical
gnark is a zero-knowledge proof system framework. In versions prior to 0.14.0, the Verify function in eddsa.go and ecdsa.go used the S value from a signature without asserting that 0 ≤ S < order, leading to a signature malleability vulnerability. Because gnark’s native EdDSA and ECDSA circuits lack essential constraints, multiple distinct witnesses can satisfy the same public inputs. In protocols where nullifiers or anti-replay checks are derived from R and S, this enables signature malleability and may allow double spending. This issue has been addressed in version 0.14.0.
CVE-2025-20248 1 Cisco 1 Ios Xr Software 2025-09-11 6 Medium
A vulnerability in the installation process of Cisco IOS XR Software could allow an authenticated, local attacker to bypass Cisco IOS XR Software image signature verification and load unsigned software on an affected device. To exploit this vulnerability, the attacker must have root-system privileges on the affected device. This vulnerability is due to incomplete validation of files during the installation of an .iso file. An attacker could exploit this vulnerability by modifying contents of the .iso image and then installing and activating it on the device. A successful exploit could allow the attacker to load an unsigned file as part of the image activation process.
CVE-2025-23369 1 Github 1 Enterprise Server 2025-09-05 8.8 High
An improper verification of cryptographic signature vulnerability was identified in GitHub Enterprise Server that allowed signature spoofing for unauthorized internal users. Instances not utilizing SAML single sign-on or where the attacker is not already an existing user were not impacted. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.12.14, 3.13.10, 3.14.7, 3.15.2, and 3.16.0. This vulnerability was reported via the GitHub Bug Bounty program.
CVE-2024-34358 1 Typo3 1 Typo3 2025-09-03 5.3 Medium
TYPO3 is an enterprise content management system. Starting in version 9.0.0 and prior to versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, and 13.1.1, the `ShowImageController` (`_eID tx_cms_showpic_`) lacks a cryptographic HMAC-signature on the `frame` HTTP query parameter (e.g. `/index.php?eID=tx_cms_showpic?file=3&...&frame=12345`). This allows adversaries to instruct the system to produce an arbitrary number of thumbnail images on the server side. TYPO3 versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, 13.1.1 fix the problem described.
CVE-2023-25574 1 Jupyter 1 Lti Jupyterhub Authenticator 2025-09-02 10 Critical
`jupyterhub-ltiauthenticator` is a JupyterHub authenticator for learning tools interoperability (LTI). LTI13Authenticator that was introduced in `jupyterhub-ltiauthenticator` 1.3.0 wasn't validating JWT signatures. This is believed to allow the LTI13Authenticator to authorize a forged request. Only users that has configured a JupyterHub installation to use the authenticator class `LTI13Authenticator` are affected. `jupyterhub-ltiauthenticator` version 1.4.0 removes LTI13Authenticator to address the issue. No known workarounds are available.
CVE-2024-49394 3 Mutt, Neomutt, Redhat 3 Mutt, Neomutt, Enterprise Linux 2025-09-02 5.3 Medium
In mutt and neomutt the In-Reply-To email header field is not protected by cryptographic signing which allows an attacker to reuse an unencrypted but signed email message to impersonate the original sender.
CVE-2025-52550 2025-09-02 N/A
E3 Site Supervisor Control (firmware version < 2.31F01) firmware upgrade packages are unsigned. An attacker can forge malicious firmware upgrade packages. An attacker with admin access to the application services can install a malicious firmware upgrade.
CVE-2024-0567 5 Debian, Fedoraproject, Gnu and 2 more 9 Debian Linux, Fedora, Gnutls and 6 more 2025-08-31 7.5 High
A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack.
CVE-2024-49393 3 Mutt, Neomutt, Redhat 3 Mutt, Neomutt, Enterprise Linux 2025-08-30 6.5 Medium
In neomutt and mutt, the To and Cc email headers are not validated by cryptographic signing which allows an attacker that intercepts a message to change their value and include himself as a one of the recipients to compromise message confidentiality.
CVE-2024-2307 1 Redhat 1 Enterprise Linux 2025-08-30 6.1 Medium
A flaw was found in osbuild-composer. A condition can be triggered that disables GPG verification for package repositories, which can expose the build phase to a Man-in-the-Middle attack, allowing untrusted code to be installed into an image being built.
CVE-2023-3347 3 Fedoraproject, Redhat, Samba 4 Fedora, Enterprise Linux, Storage and 1 more 2025-08-30 5.9 Medium
A vulnerability was found in Samba's SMB2 packet signing mechanism. The SMB2 packet signing is not enforced if an admin configured "server signing = required" or for SMB2 connections to Domain Controllers where SMB2 packet signing is mandatory. This flaw allows an attacker to perform attacks, such as a man-in-the-middle attack, by intercepting the network traffic and modifying the SMB2 messages between client and server, affecting the integrity of the data.
CVE-2025-30064 1 Cgm 1 Clininet 2025-08-29 N/A
An insufficiently secured internal function allows session generation for arbitrary users. The decodeParam function checks the JWT but does not verify which signing algorithm was used. As a result, an attacker can use the "ex:action" parameter in the VerifyUserByThrustedService function to generate a session for any user.
