IntelliJ IDEA: Improper Check for Certificate Revocation
CVE-2026-118696 is a high-severity improper check for certificate revocation vulnerability in IntelliJ IDEA from JetBrains, with a CVSS 3.1 base score of 8.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists versions 2026.2.4, 2026.1.5.1, 2025.3.6.2 as the first without the flaw, so updating IntelliJ IDEA to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update IntelliJ IDEA to 2026.2.4 or 2026.1.5.1 or 2025.3.6.2, whichever matches your release line, or a later version.
- Update PyCharm to 2026.2.4 or 2026.1.5.1 or 2025.3.6.2, whichever matches your release line, or a later version.
- Update PhpStorm to 2026.2.4 or 2026.1.5.1 or 2025.3.6.2, whichever matches your release line, or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Improper Check for Certificate Revocation
The product does not check or incorrectly checks the revocation status of a certificate.
How developers prevent this class of flaw
- Ensure that certificates are checked for revoked status.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the revoked status.
