CVE intelligence and bounded remediation
CVE-2023-30948 — Palantir Foundry Comments security vulnerability
A security defect in Foundry's Comments functionality resulted in the retrieval of attachments to comments not being gated by additional authorization checks. This could enable an authenticated user to inject a prior discovered attachment UUID into other arbitrary comments to discover it's content. This defect was fixed in Foundry Comments 2.249.0, and a patch was rolled out to affected Foundry environments. No further intervention is required at this time.

Matched remediation archetype
Authorization bypass, IDOR, and cross-tenant access
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
- Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
- Use synthetic fixtures to compare intended access matrices without accessing another user's real data.
Remediate safely
- Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
- Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
- Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
