The CVE record's CNA (WPScan) lists ACF Frontend Admin by DynamiApps versions up to and including 3.29.13 as affected. No release containing a fix is confirmed on record.

The ACF Frontend Admin by DynamiApps WordPress plugin through 3.29.13 does not restrict which PHP classes may be instantiated when it deserialises stored post content that is rendered on public-facing pages, allowing high-privilege users such as administrators to inject a PHP object which, given a suitable POP chain in another installed ACF Frontend Admin by DynamiApps WordPress plugin through 3.29.13 or in WordPress core, can be leveraged to achieve remote code execution.

EG Risk 30/100

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

BOD 26-04 binds US Federal Civilian Executive Branch agencies; for anyone else it is CISA's published timeline, a reference rather than an obligation. The directive · how EchelonGraph applies it
