RUSTSEC-2026-0510
vodozemacIn version 0.11.1 and earlier of vodozemac, Ed25519PublicKey::from_base64() and Ed25519SecretKey::from_base64() panic on malformed input instead of returning an error, if the input decodes to 31 or 33 bytes instead of the expected 32 bytes. An attacker who can supply a key to an application using vodozemac can crash it.
Impact
Ed25519 public keys are routinely received from other Matrix users and servers, so a malicious party can publish a crafted key that crashes clients parsing it.
The impact is limited to denial of service; no key disclosure or signature forgery is possible.
