CVE-2023-2249Public exploitNetwork attack vector

File read and code execution via unchecked image_blob

Published Jun 9, 2023 · Updated Apr 8, 2026

File inclusion, SSRF, and PHAR deserialization in AdvancedCoding wpForo Forum 2.1.7 and earlier allow remote authenticated users to read files. The profiles_default_cover_upload and profile_cover_upload handlers pass a comma-free image_blob value to file_get_contents without validating its path or URI scheme. Subscriber access reaches file reads and internal requests; PHAR deserialization requires Author access, PHP before 8.0, and a usable gadget chain for code execution.
