Packages

Ecosystem	Package	Affected	Fixed in
npm	uap-core	< 0.11.0	0.11.0

Details

As written in the advisory (Markdown source, shown as plain text).

## Impact Some regexes are vulnerable to regular expression denial of service (REDoS) due to overlapping capture groups. This allows remote attackers to overload a server by setting the User-Agent header in an HTTP(S) request to maliciously crafted long strings. ## Patches Please update uap-core to >= v0.11.0 Downstream packages such as uap-python, uap-ruby etc which depend upon uap-core follow different version schemes.
