Next.js: Pending `use cache` fill can leak Draft Mode content into regular responses and persisted pages
GitHub lists this reviewed advisory for next. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
4.2 medium
GitHub source severity; exploitability and local consequence require separate evidence.

Pending `use cache` fills are shared across requests for the same key without distinguishing Draft Mode requests from regular requests. When two such requests overlap, the second request receives the first request's fill: - A regular request that overlaps an editor's Draft Mode request receives unpublished content, without any authentication. - A Draft Mode request that overlaps a regular request receives published content instead of the draft. If the overlapping regular request prerenders a page — for example an on-demand prerender of a route that was not prerendered at build time — the unpublished content can be persisted into the generated page and served to all later visitors of that route until the page is revalidated. Since cached functions can be shared across routes, the poisoned page does not need to be the page the editor is previewing. Sites are affected if they enable Cache Components (or `experimental.useCache`) and serve Draft Mode previews whose cached functions return draft-dependent content.
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
