MEDIUMXSS Vulnerability in Action View tag helpers
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
There is a possible XSS vulnerability in Action View tag helpers. Passing untrusted input as hash keys can lead to a possible XSS vulnerability. This vulnerability has been assigned the CVE identifier CVE-2022-27777.
Versions Affected: ALL Not affected: NONE Fixed Versions: 7.0.2.4, 6.1.5.1, 6.0.4.8, 5.2.7.1
Impact
If untrusted data is passed as the hash key for tag attributes, there is a possibility that the untrusted data may not be properly escaped which can lead to an XSS vulnerability.
Impacted code will look something like this:
check_box_tag('thename', 'thevalue', false, aria: { malicious_input => 'thevalueofaria' })
Where the "malicious_input" variable contains untrusted data.
All users running an affected release should either upgrade or use one of the workarounds immediately.
Releases
The FIXED releases are available at the normal locations.
Workarounds
Escape the untrusted data before using it as a key for tag helper methods.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for actionview. 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.
Fix
Update actionview to 5.2.7.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-ch3h-j2vf-95pv is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-ch3h-j2vf-95pv 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-ch3h-j2vf-95pv. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-ch3h-j2vf-95pv in your dependencies?
O3 detects GHSA-ch3h-j2vf-95pv across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
