- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial

- Published: 2026-06-29 · Updated: 2026-06-30

## Affected

- yahoo elide: through 7.1.17

## Description

Elide through 7.1.17 fails to enforce @ReadPermission on client-supplied sort expressions in SortingImpl.getValidSortingRules, allowing attackers to sort collections by forbidden fields. Attackers can infer hidden field values through row ordering analysis, leaking relative field ordering across all rows via both JSON:API and GraphQL read paths.
