## What is CVE-2026-66825?

CVE-2026-66825 is a medium-severity cross-site scripting vulnerability in pivotick, published on 27 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Pivotick contains a cross-site scripting vulnerability in the sidebar property-list component. Values associated with link-like properties, such as url, uri, href, link, website, or homepage, were rendered as hyperlinks without validating their URL scheme.

An attacker able to supply or influence node or edge property data could provide a malicious value using the javascript: scheme, including variants obfuscated with whitespace or control characters. If a user clicked the generated property link, attacker-controlled JavaScript could execute in the context of the Pivotick application.

Successful exploitation could allow the attacker to access information available to the victim’s browser session or perform actions with the victim’s privileges. The vulnerability was addressed by normalizing property values and preventing URLs with non-allowlisted schemes from being rendered as clickable links.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

What it is: CVE-2026-66825 is a medium-severity cross-site scripting vulnerability in pivotick, published on 27 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-66825 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.
