Subject: Python Beaker - Deserialization of Untrasted Data which can lead to
Arbitrary code execution
Hello all,
python beaker is affected by Deserialization of untrusted data (CWE-502)
which could lead to Arbitrary code execution.
I believe it was initially pointed out the flaw on Session here:
https://github.com/bbangert/beaker/issues/35
Some improvements were made by adding a secret/HMAC but the Cache layer
still has the same flaw. I reported the flaw on cache level here:
https://github.com/bbangert/beaker/issues/191
I created a POC but didn't publish it on the ticket.
There is no CVE assigned to this.
This package exists on Fedora and Debian at least.
Should I take any extra action?
Best regards,
