    CVE-2022-23626

    Published: 8 Feb 2022Last Modified: 12 Aug 2026

    Summary: Insufficient file checks in m1k1o/blog

    Details: m1k1o/blog is a lightweight self-hosted facebook-styled PHP blog. Errors from functions `imagecreatefrom*` and `image*` have not been checked properly. Although PHP issued warnings and the upload function returned `false`, the original file (that could contain a malicious payload) was kept on the disk. Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.
