CVE-2026-85278
Published:September 04, 2026
Updated:October 12, 2026
jackson-dataformat-toml 2.15.0 before 2.18.10, 2.19.0 before 2.21.6, 2.22.0 before 2.22.2, 3.0.0 before 3.1.6 and 3.2.0 before 3.2.2: TOML dotted keys create nested tables without checking StreamReadConstraints.maxNestingDepth for each key segment, so a long dotted key bypasses the nesting limit and causes unbounded resource allocation (denial of service). The 2.19 and 2.20 lines are not fixed.
