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.
How urgent is this, really
GHSA-pvpg-9553-f979 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,333 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Liferay CMS Portal version 7.1.3 and 7.2.1 have a blind persistent cross-site scripting (XSS) vulnerability in the user name parameter to Calendar. An attacker can insert the malicious payload on the username, lastname or surname fields of its own profile, and the malicious payload will be injected and reflected in the calendar of the user who submitted the payload. An attacker could escalate its privileges in case an admin visits the calendar that injected the payload.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay.portal:release.portal.bom, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of com.liferay.portal:release.portal.bom has shipped for GHSA-pvpg-9553-f979 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-pvpg-9553-f979 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-pvpg-9553-f979. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
