CVE-2026-22001-SPHINCS-WOTS-Weak-Randomness-Forgeable-Signature
CVE-2026-22001 – SPHINCS+ WOTS+ Weak Randomness Signature Forgery Overview An implementation of the SPHINCS+ post‑quantum signature scheme uses a flawed random number generator during WOTS+ signature generation. The same nonce k is reused across multiple signatures, allowing an attacker to recove...
DEBIAN-CVE-2026-87733
An issue was discovered in the mirage-crypto-ec function before 2.2.0 for OCaml. The ECDSA functions P256,P384,P521.Dsa.pubofoctets accept 0x00, the encoding of the point at infinity, as a public key. With that public key, signatures can be forged without a private key...

CVE-2026-87733
mirage-crypto-ec for OCaml , versions before 2.2.0 , contains a flaw in the ECDSA functions {P256, P384, P521}.Dsa.pub_of_octets. The function accepts 0x00 —the encoding of the point at infinity —as a valid public key, allowing an attacker to forge ECDSA signatures without knowledge of the privat...

CVE-2026-67276
RouterOS does not compare the complete RSA public key when matching an SSH authentication request to an authorized user key, checking the key type and modulus but omitting the exponent. Because signature verification uses the client-supplied key, an attacker knowing an authorized RSA modulus can...
CVE-2026-67278
MikroTik RouterOS accepts malformed RSA/PKCS#1 v1.5 signatures during X.509 validation. Because its trust store includes a root CA with e=3 , an attacker who controls or redirects an outbound TLS connection can use the root's public certificate—without its private key—to forge a trusted intermedi...
