CVE-2026-19165

What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content. The attack does require particular conditions, which makes it less systematic.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- Already-freed memory is reused, letting the attacker reclaim it and hijack execution.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
