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
CVE-2022-28982 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 378,156 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
A cross-site scripting (XSS) vulnerability in Liferay Asset Taglib before v6.1.9 from Liferay Portal (v7.3.3 through v7.4.2) and Liferay DXP v7.3 before service pack 3 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the name of a tag.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.liferay:com.liferay.asset.taglib, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update com.liferay:com.liferay.asset.taglib to 6.1.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-28982 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2022-28982 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2022-28982. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
