No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

In Stump through 0.1.10, the updateSmartList and deleteSmartList GraphQL mutations (crates/graphql/src/mutation/smart_lists.rs) depend only on the shared AccessSmartList permission and resolve the target list at Reader access (lacking a creator check). Any authenticated user with that permission can overwrite, delete, or take over another user's smart list. (updateSmartList sets creatorId to the caller identity, and can set visibility to PRIVATE, locking out the original owner.) NOTE: this is unrelated to the graphql crate on crates.io.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
