## What is CVE-2026-67173?

CVE-2026-67173 is a medium-severity server-side request forgery vulnerability in pivotick, published on 28 Jul 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Pivotick did not validate the URL scheme of node imagePath values derived from graph data before assigning them to SVG image resources. An attacker able to supply crafted graph data could set an image path to a malicious URI.

When a victim rendered the affected graph, the browser could resolve the attacker-controlled URI and initiate an unintended request or invoke scheme-specific handling in the victim’s context. Depending on the URI, browser behaviour, and installed protocol handlers, exploitation could disclose limited client or network metadata, facilitate rendering-based tracking, or attempt to access local or internal resources.

Exploitation requires a victim to load or render graph data containing the malicious imagePath. The patch normalizes ASCII whitespace and control characters in URI schemes and restricts image paths to relative URLs or the http, https, data, and blob schemes.

Weakness: CWE-918 (Server-Side Request Forgery)

Check this codebase for CVE-2026-67173 and fix it if it is affected.

What it is: CVE-2026-67173 is a medium-severity server-side request forgery vulnerability in pivotick, published on 28 Jul 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-67173 in the wild and no public exploit code.

Affected product: pivotick. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
