An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-39313 in the wild and no public exploit code.\n\nAffected product: Simple Image Gallery. 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-2021-39313/ (Markdown: https://insights.sbomify.com/CVE-2021-39313/index.md)","id":"CVE-2021-39313","markdown":"https://insights.sbomify.com/CVE-2021-39313/index.md","name":"CVE-2021-39313","record":{"aliases":["GHSA-9j6h-6x9c-qmfv"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Attackers can inject arbitrary web scripts via the msg parameter in the Simple Image Gallery WordPress plugin, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[{"product":"simple_image_gallery","vendor":"duogeek"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","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 Simple Image Gallery WordPress plugin is vulnerable to Reflected Cross-Site Scripting via the msg parameter found in the ~/simple-image-gallery.php file which allows attackers to inject arbitrary web scripts, in versions up to and including 1.0.6.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Simple Image Gallery \u003c= 1.0.6 Reflected Cross-Site Scripting","id":"CVE-2021-39313","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"WooCommerce EnvioPack \u003c= 1.2 Reflected Cross-Site Scripting","id":"CVE-2021-39314"},"packages":[],"prev":{"headline":"True Ranker \u003c= 2.2.2 Directory Traversal/Arbitrary File Read","id":"CVE-2021-39312"},"products":["Simple Image Gallery"],"published":"2021-12-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-01-31","vendors":["Simple Image Gallery"]},"summary":"Attackers can inject arbitrary web scripts via the msg parameter in the Simple Image Gallery WordPress plugin, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2021-39313/"}
