CVE-2023-47795: Liferay Portal Document and Media widget and Liferay DXP vulnerable to stored Cross-site Scripting

Should you act?

Critical, preconditions apply

Severe if exploited, but exploitation needs conditions that may not apply to you. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• 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) >= 7.4.3.18, <= 7.4.3.101, fixed in 7.4.3.102; 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.u18, <= 7.4.13.u92, no fixed version listed. Check your lockfile, including transitive dependencies.

What it is
