Twiki

Twiki is a lightweight, self-hosted collaboration and knowledge-management platform with a modestly sized but prominent vulnerability footprint concentrated in its core product and community plugins such as ImageGalleryPlugin. The exposure recurs persistently through web-application vulnerability classes—principally cross-site scripting, cross-site request forgery, code injection, and input-handling flaws—that reflect the platform's role as a publicly accessible wiki and content-generation system. Vulnerabilities affecting Twiki tend to acquire public exploit code, consistent with the transparency and community scrutiny that open-source wiki platforms attract. Defenders should treat Twiki instances, particularly those exposed to untrusted networks or the internet, as requiring regular patching and should isolate administrative interfaces; current exploitation activity and severity figures are shown alongside this summary.
