An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-13340 exists.\n\nAffected product: Unknown SVG Support. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-13340/ (Markdown: https://insights.sbomify.com/CVE-2026-13340/index.md)","id":"CVE-2026-13340","markdown":"https://insights.sbomify.com/CVE-2026-13340/index.md","name":"CVE-2026-13340","record":{"aliases":["GHSA-2v5f-qf73-676h"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"An attacker with upload permissions can bypass SVG sanitization using .svgz files to execute scripts in victim browsers, potentially leading to account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The SVG Support WordPress plugin before 2.5.17 does not apply its SVG sanitisation to uploaded files using the .svgz extension, even though it registers and serves them as SVG, allowing a user permitted to upload SVGs (such as an Author once granted upload access) to store a script-bearing file that executes in the browser of anyone who later views it, including an administrator.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"SVG Support \u003c 2.5.17 - Author+ Stored XSS via .svgz Sanitization Bypass","id":"CVE-2026-13340","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Prompt Injection and Credential Exposure via Untrusted Analytics Data in Kong Konnect MCP","id":"CVE-2026-13341"},"packages":[],"prev":{"headline":"CubeWP Framework \u003c= 1.1.30 - Unauthenticated Arbitrary File Read via prev_icon/next_icon Parameter","id":"CVE-2026-13339"},"products":["SVG Support"],"published":"2026-08-03","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-03","vendors":["Unknown"]},"summary":"An attacker with upload permissions can bypass SVG sanitization using .svgz files to execute scripts in victim browsers, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2026-13340/"}
