This allows authenticated administrators to inject malicious Yii2 behavior configurations that execute arbitrary system commands on the server. This vulnerability represents an **unpatched variant** of the behavior injection vulnerability addressed in GHSA-255j-qw47-wjh5, affecting different endpoints through a separate code path.\n\n---","aliases":[{"alias":"CVE-2026-25498"},{"alias":"GHSA-7jx7-3846-m7w7"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/73947?format=json","purl":"pkg:composer/craftcms/cms@4.16.18","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:composer/craftcms/cms@4.16.18"},{"url":"http://public2.vulnerablecode.io/api/packages/73946?format=json","purl":"pkg:composer/craftcms/cms@5.8.22","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:composer/craftcms/cms@5.8.22"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/65261?format=json","purl":"pkg:composer/craftcms/cms@4.0.0-RC1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1468-4fdx-kbfr"},{"vulnerability":"VCID-1mb5-28xp-ckd2"},{"vulnerability":"VCID-2vn9-2cs3-vbg3"},{"vulnerability":"VCID-7y4f-ef7t-47eb"},{"vulnerability":"VCID-8u2j-17a4-q7eh"},{"vulnerability":"VCID-9enr-b6zd-mbh8"},{"vulnerability":"VCID-akrv-yqnf-1kg8"},{"vulnerability":"VCID-azr5-12f8-hfbm"},{"vulnerability":"VCID-cys8-jnmu-77ec"},{"vulnerability":"VCID-ec34-nvn3-qbcb"},{"vulnerability":"VCID-f7gc-cgka-tycr"},{"vulnerability":"VCID-hyct-5gap-7kdu"},{"vulnerability":"VCID-jeyh-3jxd-z3g6"},{"vulnerability":"VCID-jhen-vhqx-n7dr"},{"vulnerability":"VCID-jxz8-g6fq-dubw"},{"vulnerability":"VCID-kbrc-85av-nfcn"},{"vulnerability":"VCID-m5rf-usae-yfb7"},{"vulnerability":"VCID-ppet-ruae-1kav"},{"vulnerability":"VCID-qwmy-d2e8-5khw"},{"vulnerability":"VCID-qywv-vf4r-8bh9"},{"vulnerability":"VCID-twuy-wzb7-k7g3"},{"vulnerability":"VCID-vasz-rnn1-67ev"},{"vulnerability":"VCID-w9yn-1573-hyau"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:composer/craftcms/cms@4.0.0-RC1"},{"url":"http://public2.vulnerablecode.io/api/packages/73168?format=json","purl":"pkg:composer/craftcms/cms@5.0.0-RC1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-1468-4fdx-kbfr"},{"vulnerability":"VCID-1mb5-28xp-ckd2"},{"vulnerability":"VCID-39ct-cg7w-kyb6"},{"vulnerability":"VCID-4wkr-jx1w-77hn"},{"vulnerability":"VCID-5mnd-qvaq-k3am"},{"vulnerability":"VCID-5q5g-jrxm-eyhe"},{"vulnerability":"VCID-7y4f-ef7t-47eb"},{"vulnerability":"VCID-8u2j-17a4-q7eh"},{"vulnerability":"VCID-9enr-b6zd-mbh8"},{"vulnerability":"VCID-a3b5-pwyh-yugv"},{"vulnerability":"VCID-akrv-yqnf-1kg8"},{"vulnerability":"VCID-azr5-12f8-hfbm"},{"vulnerability":"VCID-cys8-jnmu-77ec"},{"vulnerability":"VCID-esma-wxje-eqh3"},{"vulnerability":"VCID-fpea-e48p-kfbn"},{"vulnerability":"VCID-hkp9-3hzv-quhk"},{"vulnerability":"VCID-hyct-5gap-7kdu"},{"vulnerability":"VCID-jeyh-3jxd-z3g6"},{"vulnerability":"VCID-jxz8-g6fq-dubw"},{"vulnerability":"VCID-kbrc-85av-nfcn"},{"vulnerability":"VCID-m5rf-usae-yfb7"},{"vulnerability":"VCID-pgm4-svq8-tfc5"},{"vulnerability":"VCID-ppet-ruae-1kav"},{"vulnerability":"VCID-qywv-vf4r-8bh9"},{"vulnerability":"VCID-rb7c-3nkc-gkeg"},{"vulnerability":"VCID-twuy-wzb7-k7g3"},{"vulnerability":"VCID-vasz-rnn1-67ev"},{"vulnerability":"VCID-vvhc-rnpr-ubey"},{"vulnerability":"VCID-w9yn-1573-hyau"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:composer/craftcms/cms@5.0.0-RC1"}],"references":[{"reference_url":"https://github.com/craftcms/cms","reference_id":"","reference_type":"","scores":[],"url":"https://github.com/craftcms/cms"},{"reference_url":"https://github.com/craftcms/cms/releases/tag/4.16.18","reference_id":"","reference_type":"","scores":[],"url":"https://github.com/craftcms/cms/releases/tag/4.16.18"},{"reference_url":"https://github.com/craftcms/cms/releases/tag/5.8.22","reference_id":"","reference_type":"","scores":[],"url":"https://github.com/craftcms/cms/releases/tag/5.8.22"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25498","reference_id":"CVE-2026-25498","reference_type":"","scores":[],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25498"},{"reference_url":"https://github.com/advisories/GHSA-7jx7-3846-m7w7","reference_id":"GHSA-7jx7-3846-m7w7","reference_type":"","scores":[],"url":"https://github.com/advisories/GHSA-7jx7-3846-m7w7"},{"reference_url":"https://github.com/craftcms/cms/security/advisories/GHSA-7jx7-3846-m7w7","reference_id":"GHSA-7jx7-3846-m7w7","reference_type":"","scores":[],"url":"https://github.com/craftcms/cms/security/advisories/GHSA-7jx7-3846-m7w7"}],"weaknesses":[{"cwe_id":470,"name":"Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection')","description":"The product uses external input with reflection to select which classes or code to use, but it does not sufficiently prevent the input from selecting improper classes or code."},{"cwe_id":937,"name":"OWASP Top Ten 2013 Category A9 -
