CVE-2022-48565: An XML External Entity (XXE) issue was discovered in Python through 3.9.1.
Noroxi assessment
Priority: Plan (action score 41/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 5% (FIRST EPSS); higher than 92.2% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: babel (AlmaLinux:8) 2.5.1-10.module_el8.6.0+2781+fed64c13; python-nose-docs (AlmaLinux:8) 1.3.7-31.module_el8.6.0+2781+fed64c13; python-psycopg2-doc (AlmaLinux:8) 2.7.5-8.module_el8.9.0+3640+8d3927b5.
Add it to your regular patch cycle. Upgrade to babel (AlmaLinux:8) 2.5.1-10.module_el8.6.0+2781+fed64c13; python-nose-docs (AlmaLinux:8) 1.3.7-31.module_el8.6.0+2781+fed64c13; python-psycopg2-doc (AlmaLinux:8) 2.7.5-8.module_el8.9.0+3640+8d3927b5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
An XML External Entity (XXE) issue was discovered in Python through 3.9.1. The plistlib module no longer accepts entity declarations in XML plist files to avoid XML vulnerabilities.
