@hapi/content: quadratic-time parsing of Content-Disposition parameters allows denial of service
GitHub lists this reviewed advisory for @hapi/content, content. 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.

source listed<= 6.0.2
### Summary `Content.disposition()` takes quadratic time when a `Content-Disposition` parameter contains a long token without `=`. One unauthenticated multipart request can block the Node.js event loop for several minutes. ### Details `Content.disposition()` reads the parameters with a global regular expression in `String.prototype.replace()`: ```js /([^\=\*\s]+)(\*)?\s*\=\s*(?:([^;'"\s]+\'[\w-]*\'[^;\s]+)|(?:\"([^"]*)\")|([^;\s]*))/g ``` The parameter name part `([^\=\*\s]+)` has no anchor. When a run of name characters has no `=` after it, the match attempt reads the full run and fails. The global scan then starts again at the next character and reads the remaining run again. The total time is proportional to the square of the run length. `@hapi/pez` calls `Content.disposition()` on the header of every part in a `multipart/form-data` body. In hapi, this occurs on each route with `payload.multipart` enabled, before the route handler and before any validation. The only size limit is the route `payload.maxBytes`, which is 1 MB by default. The fix adds an alternative that matches the full run of name characters when no `=` follows it. The scan then continues after the run, and

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. FIRST EPSS
- vendor patch
The original advisory lists fixed boundaries 6.0.3 for @hapi/content. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
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.
- NVD lastModified does not establish freshness of every associated CPE record.
