Cross-Site Scripting in bleach
All versions of bleach are vulnerable to Cross-Site Scripting. It is possible to bypass the package's HTML sanitization with payloads such as "<<script><</script>script>alert('xss');</<script><</script>script>" regardless of the passed options. This may allow attackers to execute arbitrary JavaScript in the victim's browser.
