Update meta-marked to latest version
Meta-marked 0.4.4 which we used from our git repository contains a RegexDOS attack in the marked dependency. The dependency was already updated in our meta-marked repository, but not updated in yarn. This made us still vulnerable to this ReDOS which was able to cause a DOS attack on the server when updating a note. For Details: https:/markedjs/marked/releases/tag/v0.7.0 markedjs/marked#1515 What is a ReDOS? A ReDOS attack is a DOS attack where an attacker targets a not-well-written Regular Expression. Regular expressions try to build a tree of all possibilities it can match in order to figure out if the given statement is valid or not. A ReDOS attack abuses this concept by providing a statement that doesn't match but causes extremly huge trees that simply lead to exhausting CPU usage. For more details see: https://www.owasp.org/index.php/Regular_expression_Denial_of_Service_-_ReDoS Credit: Huge thanks to @bitinerant for finding this and handling it with a responsible disclosure. Also thanks to the `marked`-team for fixing things already. Signed-off-by: Sheogorath <[email protected]>
