CVE-2022-23810Network attack vector

Authenticated file read via unsanitized template output

Published Feb 24, 2022 · Updated Aug 3, 2024

Template injection in affected Appleple a-blog cms releases allows remote authenticated users to read arbitrary files from the server. Profile usernames and default-theme entry titles are emitted into templates without sanitization, allowing attacker-controlled template syntax to be evaluated. Exploitation requires a logged-in untrusted contributor or a member permitted to set a username; only server-file disclosure is reported.
