# CVE-2023-40191: Liferay Portal and Liferay DXP vulnerable to reflected Cross-site Scripting

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.6% , percentile 49: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 49% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes com.liferay.portal:release.portal.bom (Maven) >= 7.4.3.44, <= 7.4.3.97, fixed in 7.4.3.98 ; com.liferay.portal:release.dxp.bom (Maven) >= 2023.Q3, < 2023.Q3.6, fixed in 2023.Q3.6 ; com.liferay.portal:release.dxp.bom (Maven) >= 7.4.13.u44, <= 7.4.13.u92, no fixed version listed . Check your lockfile, including transitive dependencies.
