High CVSS 7.5
CVE-2026-56859
NVD analysis in progress
Previously, DecodeElement would reset the depth counter causing it to never fire; this could lead to stack exhaustion.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can take the service offline.
- Weakness
- Resources are allocated without a cap, so simple repetition is enough to exhaust them.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
What to doFold into the next patch cycle. Start with the instances exposed to the internet.
