However, Tika reuses SAXParsers and calls reset() after each parse, which, for Xerces2 parsers, as per the documentation, removes the user-specified SecurityManager and thus removes entity expansion limits after the first parse. Apache Tika versions from 0.1 to 1.19 are therefore still vulnerable to entity expansions which can lead to a denial of service attack. Users should upgrade to 1.19.1 or later.","published_at":"2018-10-09T22:00:00Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["http://www.securityfocus.com/bid/105585","https://lists.apache.org/thread.html/88de8350cda9b184888ec294c813c5bd8a2081de8fd3666f8904bc05%40%3Cdev.tika.apache.org%3E","https://security.netapp.com/advisory/ntap-20190903-0002/","https://access.redhat.com/errata/RHSA-2019:3892"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:10:38.978515Z"},"effective_severity":null,"badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-tika","product_name":"Apache Tika","version_start":"Apache Tomcat 0.1 to 1.19","version_start_inclusive":true,"version_end":"Apache Tomcat 0.1 to 1.19","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-tika:Apache Tomcat 0.1 to 1.19:Apache Tomcat 0.1 to 1.19"}],"exploit_refs":[],"news":[],"references":[{"url":"http://www.securityfocus.com/bid/105585","source_type":"MISC","tags":[]},{"url":"https://lists.apache.org/thread.html/88de8350cda9b184888ec294c813c5bd8a2081de8fd3666f8904bc05%40%3Cdev.tika.apache.org%3E","source_type":"MAILING_LIST","tags":["mailing-list"]},{"url":"https://security.netapp.com/advisory/ntap-20190903-0002/","source_type":"MISC","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2019:3892","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2018-10-09T22:00:00Z","label":"CVE published","source":null}]}
