CVE-2022-26719

What it actually does

Memory corruption vulnerability allowing arbitrary code execution when processing maliciously crafted web content due to insufficient state management.

Why it matters to the business

Attackers can compromise user devices to steal data, install malware, or gain persistent access, increasing breach risk and remediation costs especially for organizations with high web browsing exposure; low EPSS but long public exposure since 2022 heightens urgency.

How an attack unfolds

An attacker crafts a malicious web page exploiting the memory corruption flaw; when a victim processes the content via an affected client, the flaw triggers code execution. No known threat actors or ransomware use reported.

How to fix it

Upgrade curl to commit 5ce164e0e9290c96eb7d502173426c0a135ec008 or later versions that address the state management issue.

How to confirm the fix worked

Verify the installed curl version includes commit 5ce164e0e9290c96eb7d502173426c0a135ec008; test with known malicious content samples in isolated environments.

Typical attack path

1. Attacker prepares malicious web content targeting the memory corruption
2. Victim is directed to or visits the crafted content
3. Client processes the content triggering the flaw
4. Arbitrary code executes in the victim's context

How to detect it

Review application logs for unexpected crashes or code execution during web content processing; check process execution anomalies post-browsing activity.

What your security team should do
