## What is CVE-2026-44376?

CVE-2026-44376 is a medium-severity cross-site scripting vulnerability in cubecart v6, published on 13 May 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

CubeCart is an ecommerce software solution. Prior to 6.7.0, an unauthenticated Reflected XSS vulnerability exists in the CubeCart v6.x search feature. Due to a logic flaw in classes/catalogue.class.php, user input is reflected without sanitization only when a search returns exactly one product. This flaw bypasses current filters, allowing an attacker to execute malicious JavaScript in the victim's browser, leading to session hijacking, site defacement, or phishing. This vulnerability is fixed in 6.7.0.

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

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.
