## What is CVE-2026-100190?

CVE-2026-100190 is a medium-severity cross-site scripting vulnerability in ail framework, published on 25 Sep 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

The AIL Framework crawler splash domain page (showDomain.html) is vulnerable to stored cross-site script injection (XSS). User-supplied data originating from imported crawler captures—specifically item IDs, URLs, and screenshot file paths—was interpolated directly into inline JavaScript contexts within the HTML template. This included an onclick attribute that embedded raw screenshot and URL values into a JavaScript function call, and an inline script block that assigned a screenshot value to a JavaScript variable without escaping. An attacker with a user-role API client could craft a malicious crawler capture import containing JavaScript payloads in these fields. When any user (including privileged users) subsequently viewed the affected domain page, the injected script would execute in the victim's browser context, potentially allowing session hijacking, data exfiltration, or unauthorized actions on behalf of the victim. The vulnerability is stored in the application's data layer and triggered upon page rendering, requiring no further interaction beyond loading the domain view.

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

What it is: CVE-2026-100190 is a medium-severity cross-site scripting vulnerability in ail framework, published on 25 Sep 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-100190 in the wild and no public exploit code.

Affected product: ail framework. 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.
