CVE-2023-49813Network attack vector

Unauthenticated stored script execution via unsanitized input

Published Dec 14, 2023 · Updated Apr 28, 2026

Stored cross-site scripting in WP Photo Album Plus 8.5.02.005 and earlier allows remote attackers to inject scripts into plugin-generated pages. The public advisory does not identify the affected input or rendering function; it attributes the flaw to insufficient input sanitization and output escaping. No authentication is required, but exploitation requires a user to view the stored content, which executes the injected script in that user's browser context.
