CVE-2026-27743 | BDVDB-2026-317396 Detail
SPIPreferer_spam
Description#
The SPIP referer_spam plugin versions prior to 1.3.0 contain an unauthenticated SQL injection vulnerability in the referer_spam_ajouter and referer_spam_supprimer action handlers. The handlers read the url parameter from a GET request and interpolate it directly into SQL LIKE clauses without input validation or parameterization. The endpoints do not enforce authorization checks and do not use SPIP action protections such as securiser_action(), allowing remote attackers to execute arbitrary SQL queries.
Impact#
Per CVSS v3.1: confidentiality impact high, integrity impact high, availability impact high. Attack vector: network.
Weaknesses#
- CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
