Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

Impact

Form submission values were not neutralized for spreadsheet formula characters when exported to CSV. A submission containing a value beginning with a formula trigger character (e.g.  = ,  + ,  - ,  @ ) could be interpreted as a live formula when a Control Panel user opens the export in a spreadsheet application. Form submissions can come from unauthenticated front-end visitors, so the malicious value can be supplied by an anonymous user and is later triggered by an editor opening the export.

Exploitation affects the spreadsheet application used to open the export, not the Statamic application or server; the data at risk is the form submission data the exporting user is already authorized to view.

Patches

This has been fixed in 5.73.24 and 6.20.1.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for statamic/cms. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update statamic/cms to 6.20.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h77m-qrj7-jxcw is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-h77m-qrj7-jxcw is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-h77m-qrj7-jxcw. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
