An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-102783 in the wild and no public exploit code.\n\nAffected product: balbooa.com Gridbox extension for Joomla. 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-2026-102783/ (Markdown: https://insights.sbomify.com/CVE-2026-102783/index.md)","id":"CVE-2026-102783","markdown":"https://insights.sbomify.com/CVE-2026-102783/index.md","name":"CVE-2026-102783","record":{"aliases":["GHSA-89x5-vmf9-w5cx"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla Gridbox extension","requires_auth":"none","summary":"Attackers can read files from sibling directories via path traversal in the image preview feature of the Gridbox Joomla extension.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Joomla Extension - balbooa.com - Path Traversal in image preview Gridbox \u003c 2.20.4.0 - Gridbox contains the same prefix-only containment logic in its site UploaderHelper . The showImage action resolves a request-controlled path, calls that helper, and then returns the image. If image decoding is unavailable or fails, the action streams the file directly. An existing image in a sibling directory such as images-backup can therefore satisfy the current containment test even though it is outside the configured images root. The route restricts the file extension to Gridbox image types, which materially limits the read primitive. The default media root is images ; the effective site setting was not independently verified. No prefix-matching sibling directory was found alongside the site’s images directory. The finding is rated Low rather than presented as arbitrary file disclosure.","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":"Joomla Extension - balbooa.com - Path Traversal in image preview Gridbox \u003c 2.20.4.0","id":"CVE-2026-102783","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Joomla Extension - balbooa.com - CSRF in language installation feature Gridbox \u003c 2.20.4.0","id":"CVE-2026-102784"},"packages":[],"prev":{"headline":"Joomla Extension - ordasoft.com - Unauthenticated SQL injection in OrdaSoft Simple Membership \u003c 7.4.0","id":"CVE-2026-102782"},"products":["Gridbox extension for Joomla"],"published":"2026-10-08","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-09","vendors":["balbooa.com"]},"summary":"Attackers can read files from sibling directories via path traversal in the image preview feature of the Gridbox Joomla extension.","url":"https://insights.sbomify.com/CVE-2026-102783/"}
