CVE-2026-102359 1 Yuzutech 1 Kroki 2026-11-06 7.5 High
Kroki creates diagrams from textual descriptions. Prior to 0.31.2, the TikZ backend's tikz/tikz2svg guard used when KROKI_SAFE_MODE is enabled blocks only \verbatiminput while allowing native TeX file-read primitives including \openin, \read, \input, and \include. TeX Live's permissive openin_any setting remains active, so an unauthenticated actor can submit crafted LaTeX to POST /tikz/svg or the generic diagram API and cause the renderer to read any file accessible to the Kroki container user. The file contents are rendered into the returned SVG, which may disclose mounted secrets, configuration data, credentials, private keys, or process environment data. The -no-shell-escape option prevents shell execution but does not restrict these native file operations. This issue is fixed in version 0.31.2.
CVE-2026-102356 1 Yuzutech 1 Kroki 2026-11-06 5 Medium
Kroki creates diagrams from textual descriptions. From 0.26.0 until 0.31.2, the optional Mermaid companion's mermaid/src/worker.js renders attacker-controlled flowchart image nodes in headless Chromium without a network request policy, even when KROKI_SAFE_MODE is set to secure. An actor who can submit Mermaid source and satisfy any authentication or authorization configured by the deployment can cause the companion to issue HTTP or HTTPS GET requests when requesting PNG output. Exploitation requires the Mermaid companion, PNG rendering through its headless Chromium process, a diagram-submission path available to the actor, and network reachability from the companion to the target. The demonstrated impact is limited to blind request reachability and possible state-changing GET endpoints; response exfiltration, cloud metadata access, port scanning, and access beyond the companion's network reachability are not established. This issue is fixed in version 0.31.2.
