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-2021-29620 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
Report portal is an open source reporting and analysis framework. Starting from version 3.1.0 of the service-api XML parsing was introduced. Unfortunately the XML parser was not configured properly to prevent XML external entity (XXE) attacks. This allows a user to import a specifically-crafted XML file which imports external Document Type Definition (DTD) file with external entities for extraction of secrets from Report Portal service-api module or server-side request forgery. This will be resolved in the 5.4.0 release.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.epam.reportportal:service-api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update com.epam.reportportal:service-api to 5.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2021-29620 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-2021-29620 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2021-29620. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
