CVE-2026-78426 Logout bypass via alternate JWT spelling

The NeuVector JWT verifier accepts noncanonical Base64URL encodings of the same RSA signature field. An attacker holding a valid JWT that has not expired, but was logged out of NeuVector, can continue using the non-expired token with equivalent spelling of the RSA signature field until the token...

CVE-2026-78426: Incorrect Authorization

The NeuVector JWT verifier accepts noncanonical Base64URL encodings of the same RSA signature field. An attacker holding a valid JWT that has not expired, but was logged out of NeuVector, can continue using the non-expired token with equivalent spelling of the RSA signature field until the token...

CVE-2026-89086

In the jose package before 0.11.0 for OCaml, library calls to validate an RSA signature only confirm that PKCS 1 decoding succeeds, and proceed to declare the signature valid without the required steps that involve the public key...

CVE-2026-89086

CVE-2026-89086 affects the jose package for OCaml, versions before 0.11.0. The vulnerability lies in RSA signature validation: library calls only confirm that PKCS #1 decoding succeeds and then declare the signature valid, skipping the required steps that involve the public key . This means a mal...

OSEC-2026-19 JOSE: missing RSA signature verification

The opam package "jose" does not validate any RSA signature. It checks the encoding being PKCS1, but does not verify with the public key. Reproduction With jose 0.10.0, the code below signs two tokens with the same key and glues one's payload onto the other's signature: OCaml let =...

CVE-2026-89086: Improper Verification of Cryptographic Signature

PT-2026-89582

Name of the Vulnerable Software and Affected Versions jose versions prior to 0.11.0 Description The jose package for OCaml fails to properly validate RSA signatures. The library only confirms that PKCS 1 decoding succeeds but does not perform the necessary verification steps using the public key,...

The vulnerability of the SSH protocol implementation in the RouterOS operating system of MikroTik allows a hacker to bypass security restrictions and gain read-only access to data.

The vulnerability of the SSH protocol implementation in the RouterOS operating system of MikroTik is related to errors in verifying the cryptographic signature during the incorrect comparison of the RSA public key assigned to the user. Exploiting this vulnerability allows a malicious actor to...

CVE-2026-67278

MikroTik RouterOS accepts malformed RSA/PKCS1 v1.5 signatures across RSA-based services, including TLS/X.509 certificate validation and SSH host-key authentication. Because its trust store includes an e=3 root CA, an attacker controlling or redirecting an outbound RouterOS TLS connection can use...

MikroTik RouterOS accepts malformed RSA/PKCS1 v1.5 signatures during X.509 validation. Because its trust store includes an e=3 root CA, an attacker controlling or redirecting an outbound RouterOS TLS connection can use the root’s public certificate - without its private key - to forge a trusted...

librenswan: IKEv2 Denial of Service via RSA-SHA1 (PKCS#1 RSASSA-PKCS1-v1_5) authentication payload

A flaw was found in Libreswan's implementation of IKEv2 authentication when processing signatures utilizing the RSASSA-PKCS1-v15 scheme. The RSAauthenticatehashsignaturepkcs115rsa function does not correctly validate the DER encoding of the ASN.1 digest. A remote, unauthenticated attacker could...
