Summary

A web-accessible backdoor, with resultant SSRF, exists in Tp-shop 2.0.5 through 2.0.8, which allows remote attackers to obtain sensitive information, attack intranet hosts, or possibly trigger remote command execution, because /vendor/phpdocumentor/reflection-docblock/tests/phpDocumentor/Reflection/DocBlock/Tag/LinkTagTeet.php writes data from the "down_url" URL into the "bddlj" local file if the attacker knows the backdoor "jmmy" parameter.

Exploit prediction

4.66% chance of exploitation in the next 30 days, higher than 91% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
