Amazon Linux 2023 Security Advisory: ALAS2023-2025-1127
Advisory Released Date: 2025-08-08
Advisory Updated Date: 2025-08-08
Severity:
Medium
Issue Overview:
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. (CVE-2025-52999)
Affected Packages:
jackson-core
Issue Correction:
