A improper verification of cryptographic signature vulnerability in Fortinet FortiOS 7.6.0 through 7.6.3, FortiOS 7.4.0 through 7.4.8, FortiOS 7.2.0 through 7.2.11, FortiOS 7.0.0 through 7.0.17, FortiProxy 7.6.0 through 7.6.3, FortiProxy 7.4.0 through 7.4.10, FortiProxy 7.2.0 through 7.2.14, FortiProxy 7.0.0 through 7.0.21, FortiSwitchManager 7.2.0 through 7.2.6, FortiSwitchManager 7.0.0 through 7.0.5 allows an unauthenticated attacker to bypass the FortiCloud SSO login authentication via a crafted SAML response message.
CVE-2026-20965 1 Microsoft 2 Azure Portal Windows Admin Center, Windows Admin Center 2026-02-26 7.5 High
Improper verification of cryptographic signature in Windows Admin Center allows an authorized attacker to elevate privileges locally.
CVE-2026-1568 1 Rapid7 1 Insightvm 2026-02-26 9.6 Critical
Rapid7 InsightVM versions beforeĀ 8.34.0 contain a signature verification issue on theĀ Assertion Consumer Service (ACS) cloud endpoint that could allow an attacker to gain unauthorized access to InsightVM accounts setup via "Security Console" installations, resulting in full account takeover. The issue occurs due to the application processing these unsigned assertions and issuing session cookies that granted access to the targeted user accounts. This has been fixed in version 8.34.0 of InsightVM.
CVE-2026-23687 2 Sap, Sap Se 2 Sap Basis, Sap Netweaver And Abap Platform 2026-02-26 8.8 High
SAP NetWeaver Application Server ABAP and ABAP Platform allows an authenticated attacker with normal privileges to obtain a valid signed message and send modified signed XML documents to the verifier. This may result in acceptance of tampered identity information, unauthorized access to sensitive user data and potential disruption of normal system usage.
CVE-2025-12006 1 Supermicro 1 Mbd-x12stw 2026-02-26 7.2 High
There is a vulnerability in the Supermicro BMC firmware validation logic at Supermicro MBD-X12STW-F . An attacker can update the system firmware with a specially crafted image.
CVE-2026-22866 1 Ensdomains 1 Ens-contracts 2026-02-26 N/A
Ethereum Name Service (ENS) is a distributed, open, and extensible naming system based on the Ethereum blockchain. In versions 1.6.2 and prior, the `RSASHA256Algorithm` and `RSASHA1Algorithm` contracts fail to validate PKCS#1 v1.5 padding structure when verifying RSA signatures. The contracts only check if the last 32 (or 20) bytes of the decrypted signature match the expected hash. This enables Bleichenbacher's 2006 signature forgery attack against DNS zones using RSA keys with low public exponents (e=3). Two ENS-supported TLDs (.cc and .name) use e=3 for their Key Signing Keys, allowing any domain under these TLDs to be fraudulently claimed on ENS without DNS ownership. Apatch was merged at commit c76c5ad0dc9de1c966443bd946fafc6351f87587. Possible workarounds include deploying the patched contracts and pointing DNSSECImpl.setAlgorithm to the deployed contract.
CVE-2024-2307 1 Redhat 1 Enterprise Linux 2026-02-25 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-2026-23967 1 Juneandgreen 1 Sm-crypto 2026-02-25 7.5 High
sm-crypto provides JavaScript implementations of the Chinese cryptographic algorithms SM2, SM3, and SM4. A signature malleability vulnerability exists in the SM2 signature verification logic of the sm-crypto library prior to version 0.3.14. An attacker can derive a new valid signature for a previously signed message from an existing signature. Version 0.3.14 patches the issue.
CVE-2026-23965 1 Juneandgreen 1 Sm-crypto 2026-02-25 7.5 High
sm-crypto provides JavaScript implementations of the Chinese cryptographic algorithms SM2, SM3, and SM4. A signature forgery vulnerability exists in the SM2 signature verification logic of sm-crypto prior to version 0.4.0. Under default configurations, an attacker can forge valid signatures for arbitrary public keys. If the message space contains sufficient redundancy, the attacker can fix the prefix of the message associated with the forged signature to satisfy specific formatting requirements. Version 0.4.0 patches the issue.
CVE-2020-1464 1 Microsoft 22 Windows 10, Windows 10 1507, Windows 10 1607 and 19 more 2026-02-23 7.8 High
A spoofing vulnerability exists when Windows incorrectly validates file signatures. An attacker who successfully exploited this vulnerability could bypass security features and load improperly signed files. In an attack scenario, an attacker could bypass security features intended to prevent improperly signed files from being loaded. The update addresses the vulnerability by correcting how Windows validates file signatures.
CVE-2026-2968 1 Cesanta 1 Mongoose 2026-02-23 3.7 Low
A vulnerability was detected in Cesanta Mongoose up to 7.20. This impacts the function mg_chacha20_poly1305_decrypt of the file /src/tls_chacha20.c of the component Poly1305 Authentication Tag Handler. The manipulation results in improper verification of cryptographic signature. The attack may be launched remotely. This attack is characterized by high complexity. The exploitability is said to be difficult. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2026-25922 1 Goauthentik 1 Authentik 2026-02-18 8.8 High
authentik is an open-source identity provider. Prior to 2025.8.6, 2025.10.4, and 2025.12.4, when using a SAML Source that has the option Verify Assertion Signature under Verification Certificate enabled and not Verify Response Signature, or does not have the Encryption Certificate setting under Advanced Protocol settings configured, it was possible for an attacker to inject a malicious assertion before the signed assertion that authentik would use instead. authentik 2025.8.6, 2025.10.4, and 2025.12.4 fix this issue.
CVE-2025-32060 1 Bosch 1 Infotainment System Ecu 2026-02-18 6.7 Medium
The system suffers from the absence of a kernel module signature verification. If an attacker can execute commands on behalf of root user (due to additional vulnerabilities), then he/she is also able to load custom kernel modules to the kernel space and execute code in the kernel context. Such a flaw can lead to taking control over the entire system. First identified on Nissan Leaf ZE1 manufactured in 2020.
CVE-2026-25793 1 Slack 1 Nebula 2026-02-18 8.1 High
Nebula is a scalable overlay networking tool. In versions from 1.7.0 to 1.10.2, when using P256 certificates (which is not the default configuration), it is possible to evade a blocklist entry created against the fingerprint of a certificate by using ECDSA Signature Malleability to use a copy of the certificate with a different fingerprint. This issue has been patched in version 1.10.3.
CVE-2026-2625 1 Rust-rpm-sequoia 1 Rust-rpm-sequoia 2026-02-18 4.0 Medium
No description is available for this CVE.
CVE-2024-23480 1 Zscaler 1 Client Connector 2026-02-17 7.5 High
A fallback mechanism in code sign checking on macOS may allow arbitrary code execution. This issue affects Zscaler Client Connector on MacOS prior to 4.2.
CVE-2026-23992 1 Theupdateframework 1 Go-tuf 2026-02-17 5.9 Medium
go-tuf is a Go implementation of The Update Framework (TUF). Starting in version 2.0.0 and prior to version 2.3.1, a compromised or misconfigured TUF repository can have the configured value of signature thresholds set to 0, which effectively disables signature verification. This can lead to unauthorized modification to TUF metadata files is possible at rest, or during transit as no integrity checks are made. Version 2.3.1 fixes the issue. As a workaround, always make sure that the TUF metadata roles are configured with a threshold of at least 1.
