## What is CVE-2026-71445?

CVE-2026-71445 is a high-severity cross-site scripting vulnerability in ail-project ail-framework, published on 6 Aug 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

AIL Framework contained a reflected cross-site scripting vulnerability in the /tag/add_tags endpoint. When an error occurred while processing a tag operation, the application returned the error value directly as an HTML response using str(res[0]).

If attacker-controlled input was included in the generated error message, a crafted request could cause arbitrary HTML or JavaScript to be reflected in the response without appropriate output encoding. An attacker could exploit the vulnerability by convincing an authenticated AIL Framework user to open a specially crafted link.

Successful exploitation could allow JavaScript to execute in the victim’s browser within the security context of the AIL Framework application. Depending on the victim’s privileges and the application’s protections, the attacker could perform actions using the victim’s session, access information available to the victim, or modify data through authenticated application requests.

The vulnerability requires user interaction because the authenticated victim must follow or open the crafted request. The attacker does not necessarily require an AIL Framework account, provided that the crafted request can be delivered to an already authenticated user.

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

Check this codebase for CVE-2026-71445 and fix it if it is affected.

What it is: CVE-2026-71445 is a high-severity cross-site scripting vulnerability in ail-project ail-framework, published on 6 Aug 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-2026-71445 in the wild and no public exploit code.

Affected product: ail-project 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.
