CVE-2026-34993
ADVISORY - githubSummary
Summary
Using CookieJar.load() with untrusted input may allow arbitrary code execution.
Impact
Most applications using this function will be doing so with the user's own data, so this is unlikely to affect many applications.
Workaround
If an application does allow attacker controlled files to be loaded, a workaround on older releases would be to sanitise the files before loading.
