CVE-2026-116205: YesWiki before 4.7.0 Unauthenticated SSRF via [[|URL]] Raw-Inclusion Syntax

Noroxi assessment

Priority: Monitor (action score 27/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.51% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: YesWiki yeswiki 4.7.0.

Low priority for now. Upgrade to YesWiki yeswiki 4.7.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

YesWiki before 4.7.0 contains an unauthenticated server-side request forgery vulnerability that allows remote attackers to fetch arbitrary URLs by supplying [[|URL]] wiki syntax to the render handler. Attackers can pass the syntax in the content parameter of the page render handler to reach internal hosts and ports and read their responses.
