## What is CVE-2026-79701?

CVE-2026-79701 is a medium-severity vulnerability in joomshaper.com SP Page Builder (Pro) extension for Joomla, published on 14 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Joomla Extension - joomshaper.com - Unauthenticated CAPTCHA Bypass in Module Context in the Contact, Opt-in and Form Builder Addons in SP Page Builder Pro 3.2.6 - 5.6.1p2 and 6.0.0 - 6.9.0 - In the ajax_contact, optin_form and form_builder addons, the result returned by the CAPTCHA plugin's onCheckAnswer event was discarded and replaced with a test for a non-empty string whenever the request-supplied view_type parameter equalled module. Submitting view_type=module together with any arbitrary token value therefore passed verification. This affected every instance of these addons placed inside an SP Page Builder module, irrespective of the CAPTCHA type configured for the site, and the view_type parameter was never validated against the context in which the form was actually rendered.

Weakness: CWE-807 (Reliance on Untrusted Inputs in a Security Decision)

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.
