The CVE record names the fixed release — apply it.

Ente provides end-to-end encrypted cloud services and security tools. Prior to server image 2026.07.09, the POST /emergency-contacts/approve-recovery endpoint authorized approval using a client-supplied userID and updated an emergency recovery session using only its client-supplied recovery-session UUID. An accepted emergency contact could submit the contact's own identifier, transition the victim's session from WAITING to READY, clear wait_till, retrieve recovery information, and continue account recovery before the owner-configured notice period expired. Exploitation of the approval bypass required the victim to have previously added and accepted the attacker as an emergency contact, and it did not create recovery rights for an arbitrary account. Separately, the same insufficiently scoped update pattern affected the reject and stop recovery transitions, allowing a user who knew another recovery-session UUID to potentially cancel a session to which the user was not a party. This issue is fixed in server image 2026.07.09.

EG Risk 48/100

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.

SSVC (CISA's decision table, applied by EchelonGraph)Track at low, Track* at medium and Attend at high mission impact.

The CVE record names the fixed release. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation public PoC (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".

The score's inputs: In CISA KEV no (CISA's KEV catalog) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Whether your system is publicly exposed is yours to answer. 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
