A Polymorphic Typing issue was discovered in FasterXML jackson-databind before 2.9.10.
Noroxi assessment
Priority: Plan (action score 40/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 4.9% (FIRST EPSS); higher than 92% 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: apache-commons-collections (AlmaLinux:8) 3.2.2-10.module_el8.5.0+2577+9e95fe00; apache-commons-lang (AlmaLinux:8) 2.6-21.module_el8.5.0+2577+9e95fe00; bea-stax-api (AlmaLinux:8) 1.2.0-16.module_el8.5.0+2577+9e95fe00.
Add it to your regular patch cycle. Upgrade to apache-commons-collections (AlmaLinux:8) 3.2.2-10.module_el8.5.0+2577+9e95fe00; apache-commons-lang (AlmaLinux:8) 2.6-21.module_el8.5.0+2577+9e95fe00; bea-stax-api (AlmaLinux:8) 1.2.0-16.module_el8.5.0+2577+9e95fe00 or later.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
