CVE-2025-52999: jackson-core Has Potential for StackoverflowError if user parses an input file that contains very deeply nested data

Noroxi assessment

Priority: Monitor (action score 34/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.77% (FIRST EPSS); higher than 55.9% 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; apache-commons-net (AlmaLinux:8) 3.6-3.module_el8.5.0+2577+9e95fe00.

Low priority for now. 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; apache-commons-net (AlmaLinux:8) 3.6-3.module_el8.5.0+2577+9e95fe00 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

jackson-core contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. In versions prior to 2.15.0, if a user parses an input file and it has deeply nested data, Jackson could end up throwing a StackoverflowError if the depth is particularly large. jackson-core 2.15.0 contains a configurable limit for how deep Jackson will traverse in an input document, defaulting to an allowable depth of 1000. jackson-core will throw a StreamConstraintsException if the limit is reached. jackson-databind also benefits from this change because it uses jackson-core to parse JSON inputs. As a workaround, users should avoid parsing input files from untrusted sources.
