Thank you Benjamin Peterson.\n\nUpdate to 3.1.4 (boo#1168280, CVE-2020-6817):\n\n* ``bleach.clean`` behavior parsing style attributes could result in a\n  regular expression denial of service (ReDoS).\n  Calls to ``bleach.clean`` with an allowed tag with an allowed\n  ``style`` attribute were vulnerable to ReDoS. For example,\n  ``bleach.clean(..., attributes={'a': ['style']})``.\n* Style attributes with dashes, or single or double quoted values are\n  cleaned instead of passed through.\n\nupdate to 3.1.3 (boo#1167379, CVE-2020-6816):\n\n* Add relative link to code of conduct. (#442)\n* Drop deprecated 'setup.py test' support. (#507)\n* Fix typo: curren -> current in tests/test_clean.py (#504)\n* Test on PyPy 7\n* Drop test support for end of life Python 3.4\n* ``bleach.clean`` behavior parsing embedded MathML and SVG content\n  with RCDATA tags did not match browser behavior and could result in\n  a mutation XSS.\n  Calls to ``bleach.clean`` with ``strip=False`` and ``math`` or\n  ``svg`` tags and one or more of the RCDATA tags ``script``,\n  ``noscript``, ``style``, ``noframes``, ``iframe``, ``noembed``, or\n  ``xmp`` in the allowed tags whitelist were vulnerable to a mutation\n  XSS.\n",null,[],[],[],[14,16,18],{"_key":15},"CVE-2020-6816",{"_key":17},"CVE-2020-6817",{"_key":19},"CVE-2021-23980",[],[],[23,24,25],{"_key":15},{"_key":17},{"_key":19},"2021-04-14T14:51:29Z","2026-02-04T03:50:20.948699Z",{"cisa_kev":29,"cisa_ransomware":29,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[31,37,42,46,50,55,59],{"url":32,"sources":33,"tags":35},"https://lists.opensuse.org/archives/list/security-announce@lists.opensuse.org/thread/YFAKMJGUZHUTZ53ZAID6PRVP5MSLXPGV/",[34],"osv_opensuse",[36],"Advisory",{"url":38,"sources":39,"tags":40},"https://bugzilla.suse.com/1167379",[34],[41],"REPORT",{"url":43,"sources":44,"tags":45},"https://bugzilla.suse.com/1168280",[34],[41],{"url":47,"sources":48,"tags":49},"https://bugzilla.suse.com/1184547",[34],[41],{"url":51,"sources":52,"tags":53},"https://www.suse.com/security/cve/CVE-2020-6816",[34],[54],"WEB",{"url":56,"sources":57,"tags":58},"https://www.suse.com/security/cve/CVE-2020-6817",[34],[54],{"url":60,"sources":61,"tags":62},"https://www.suse.com/security/cve/CVE-2021-23980",[34],[54],[],[],[],[67],{"ecosystem":68,"name":69,"vendor":70,"product":71,"cpe_part":9,"purl_type":72,"purl_namespace":70,"purl_name":71,"source":9,"versions":73},"openSUSE","python-bleach","opensuse","python-bleach&distro=openSUSE Leap 15.2","rpm",[74],{"version":75,"is_range":76,"range_type":77,"version_start":9,"version_start_type":9,"version_end":78,"version_end_type":79,"fixed_in":9},"lt3_1_5_lp152_2_3_1",true,"ecosystem","3.1.5-lp152.2.3.1","excluding"]
