TikiWiki CMS/Groupware before 6.7 LTS and before 8.4 allows remote attackers to execute arbitrary PHP code via a crafted serialized object in the (1) cookieName to lib/banners/bannerlib.php; (2) printpages or (3) printstructures parameter to (a) tiki-print_multi_pages.php or (b) tiki-print_pages.php; or (4) sendpages, (5) sendstructures, or (6) sendarticles parameter to tiki-send_objects.php, which is not properly handled when processed by the unserialize function.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 9.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 63%
- Percentil entre todas las CVEs puntuadas: 99
- Fecha de la puntuación: 6/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
💥 Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
