If the collector exposes allowed classes property, this configuration can be bypassed.\nIt means that the log socket collector is vulnerable to deserialization of untrusted data, eventually causing DoS.\n\n\nNB: Decanter log socket collector is not installed by default. Users who have not installed Decanter log socket are not impacted by this issue.\n\nThis issue affects Apache Karaf Decanter before 2.12.0.\n\nUsers are recommended to upgrade to version 2.12.0, which fixes the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","score":3.7},"cwes":["CWE-502"],"references":["https://lists.apache.org/thread/dc5wmdn6hyc992olntkl75kk04ndzx34","http://www.openwall.com/lists/oss-security/2026/01/24/1"],"products":["apache:karaf_decanter"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2026-24656","score":0.00681,"percentile":0.52465,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-jmw5-58c7-587h","url":"https://osv.dev/vulnerability/GHSA-jmw5-58c7-587h","summary":"Apache Karaf Decanter has Deserialization of Untrusted Data in its Log Socket Collector","modified":"2026-02-03T03:07:29.196463Z","packages":[{"ecosystem":"Maven","name":"org.apache.karaf.decanter.collector:org.apache.karaf.decanter.collector.log.socket","purl":"pkg:maven/org.apache.karaf.decanter.collector/org.apache.karaf.decanter.collector.log.socket","ranges":["<2.12.0"],"fixed":["2.12.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
