Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-36048 in the wild and no public exploit code.\n\nAffected product: zulip. 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-2022-36048/ (Markdown: https://insights.sbomify.com/CVE-2022-36048/index.md)","id":"CVE-2022-36048","markdown":"https://insights.sbomify.com/CVE-2022-36048/index.md","name":"CVE-2022-36048","record":{"aliases":["GHSA-vg5m-mf9x-j452"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Zulip Server","requires_auth":"low_privilege","summary":"An attacker can leak viewer IP addresses and browser fingerprints by bypassing the image proxy in Zulip Server when image previews are enabled.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"zulip","vendor":"zulip"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-436","name":"Interpretation Conflict"}],"description":"Zulip is an open-source team collaboration tool with topic-based threading that combines email and chat. When displaying messages with embedded remote images, Zulip normally loads the image preview via a go-camo proxy server. However, an attacker who can send messages could include a crafted URL that tricks the server into embedding a remote image reference directly. This could allow the attacker to infer the viewer’s IP address and browser fingerprinting information. This vulnerability is fixed in Zulip Server 5.6. Zulip organizations with image and link previews [disabled](https://zulip.com/help/allow-image-link-previews) are not affected.","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":"IP address leak via image proxy bypass in Zulip Server","id":"CVE-2022-36048","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Flux2 Helm Controller denial of service","id":"CVE-2022-36049"},"packages":[],"prev":{"headline":"Unexpected server crash in Next.js version 12.2.3","id":"CVE-2022-36046"},"products":["zulip"],"published":"2022-08-31","related":[{"cvss_score":8.6,"headline":"RabbitMQ exposes ports with weak default secrets in Zulip Server","id":"CVE-2021-43799","kev_date_added":null,"published":"2022-01-25"},{"cvss_score":8,"headline":"Crafted link in Zulip message can cause disclosure of credentials","id":"CVE-2022-35962","kev_date_added":null,"published":"2022-08-29"},{"cvss_score":7.5,"headline":"Auth bypass in zulip","id":"CVE-2016-4427","kev_date_added":null,"published":"2022-07-28"},{"cvss_score":6.8,"headline":"Cross-site Scripting (XSS) - Stored in zulip/zulip","id":"CVE-2021-3866","kev_date_added":null,"published":"2022-01-20"},{"cvss_score":6.5,"headline":"Unauthorized user can register an account in specific configurations in Zulip","id":"CVE-2023-28623","kev_date_added":null,"published":"2023-05-19"},{"cvss_score":6.5,"headline":"Ineffective expiration validation for invitation links in Zulip","id":"CVE-2021-43791","kev_date_added":null,"published":"2021-12-02"},{"cvss_score":6.1,"headline":"Zulip: Path Traversal in Import","id":"CVE-2026-26058","kev_date_added":null,"published":"2026-04-03"}],"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":"2025-04-23","vendors":["zulip"]},"summary":"An attacker can leak viewer IP addresses and browser fingerprints by bypassing the image proxy in Zulip Server when image previews are enabled.","url":"https://insights.sbomify.com/CVE-2022-36048/"}
