What this means

JetBrains products, including IntelliJ IDEA, PyCharm, and others, before specific versions, trust revoked intermediate certificates in their embedded browser. The weakness is an improper check for certificate revocation. Affected versions vary by product.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Public exploit evidence

No public exploit reference is identified in the imported evidence. This is not a claim that no exploit exists.
