    Regular Expression Denial of Service (ReDoS)

    bleach is a whitlist-based HTML sanitizing library that escapes or strips markup and attributes.

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via the LinkifyFilter.handle_email_addresses() function. An attacker can cause excessive CPU consumption by submitting specially crafted large non-email input to the email linkification path when the parse_email option is enabled. This is only exploitable if the consuming application enables the parse_email=True option and allows untrusted user input of sufficient size to reach the linkification process without input limits or timeouts.

    How to fix Regular Expression Denial of Service (ReDoS)?

    There is no fixed version for bleach.
