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-2026-107503 in the wild and no public exploit code.\n\nAffected product: Eclipse Ditto Ditto Explorer UI. 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-2026-107503/ (Markdown: https://insights.sbomify.com/CVE-2026-107503/index.md)","id":"CVE-2026-107503","markdown":"https://insights.sbomify.com/CVE-2026-107503/index.md","name":"CVE-2026-107503","record":{"aliases":["GHSA-8767-g5qv-9jcf","GHSA-g8w6-jp67-cwcc"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Eclipse Ditto Explorer UI","requires_auth":"none","summary":"Attackers can steal user tokens by tricking victims into visiting a crafted link that redirects authentication to a malicious server.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:L/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"},{"id":"CWE-522","name":"Insufficiently Protected Credentials"},{"id":"CWE-15","name":"External Control of System or Configuration Setting"}],"description":"In Eclipse Ditto versions 3.6.0 to 3.8.13 and 3.9.0 to 3.9.7, the Ditto Explorer UI loads its complete environment configuration, including the Ditto API URI and the OpenID Connect (OIDC) provider settings, from an arbitrary\ncross-origin URL supplied in the environmentsURL query parameter. It adopts this configuration without user confirmation and persists it in the browser's localStorage. A crafted link can therefore set an attacker-controlled OIDC\nauthority with autoSso enabled. The UI then automatically starts a login at the genuine identity provider but exchanges the returned authorization code together with its PKCE code_verifier at an attacker-controlled token\nendpoint. This lets the attacker redeem the code for the victim's access and refresh tokens. Alternatively, an attacker-controlled api_uri causes the UI to send the victim's bearer token or Basic credentials to the attacker. Because\nthe configuration is persisted, later visits to the UI without the crafted link repeat the token theft. In versions 3.9.0 to 3.9.7, the Swagger UI OIDC integration of the Helm chart and the Docker Compose deployment is affected in\nthe same way, but requires the user to start the login. The issue is fixed in 3.8.14 and 3.9.8.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Open redirect in Ditto Explorer UI","id":"CVE-2026-107503","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"Simple Banner \u003c 3.3.3 - Authenticated Privilege Escalation via User Permissions Setting","id":"CVE-2026-107506"},"packages":[],"prev":{"headline":"Out-of-bounds read vulnerability in QTextCodec TSCII encoding impacts Qt","id":"CVE-2026-107472"},"products":["Ditto Explorer UI"],"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":"2026-10-15","vendors":["Eclipse Ditto"]},"summary":"Attackers can steal user tokens by tricking victims into visiting a crafted link that redirects authentication to a malicious server.","url":"https://insights.sbomify.com/CVE-2026-107503/"}
