The WP Photo Album Plus plugin for WordPress is vulnerable to Remote Code Execution in all versions via the wppa_image_magick function. This is due to insufficient sanitization of the multipart upload filename before concatenation into an ImageMagick command string executed via exec(), with only escapeshellcmd() applied to the whole command rather than quoting individual arguments. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute code on the server. escapeshellcmd() escapes shell metacharacters but does not prevent argument injection because spaces remain as argument separators, and the filename sanitization applied at the database layer is never applied to the physical temporary file path used for ImageMagick processing.
CVE-2026-87909
This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
