CVE-2022-36350Network attack vector

Arbitrary script execution in visitors' browsers

Published Aug 23, 2022 · Updated Jun 30, 2025

Stored XSS in PukiWiki 1.3.1 through 1.5.3 allows remote attackers to run arbitrary scripts in visitors' browsers via unspecified vectors. The published advisory does not identify the input field, storage locus, or missing encoding operation that admits the script. Exploitation requires a visitor to open an affected wiki page; the script then runs in that site's browser security context.
