description
The richdocumentscode Nextcloud app before 26.4.303 is affected when using its built-in CODE Server. An unauthenticated remote attacker may execute operating-system commands while that server is not running, including after a restart; standalone Collabora Online servers are not affected.
mitigation
Upgrade richdocumentscode to version 26.4.303 or later. Prioritize systems using the built-in CODE Server and minimize externally reachable exposure during restarts until the update is applied.
fixed in 26.4.303
outcome
Contextual: an exploit technique exists, but no deterministic check could cover this one.
