How severe is CVE-2024-11680?
CVE-2024-11680 is rated Critical with a CVSS score of 9.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2024-11680?
Yes. A fix has been recorded for CVE-2024-11680. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.

CVE-2024-11680 affects projectsend:projectsend. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
- affected< r1720
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
