An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2025-48700 in the wild since at least 20 Apr 2026.\n\nAffected product: Synacor Zimbra Collaboration Suite. 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-2025-48700/ (Markdown: https://insights.sbomify.com/CVE-2025-48700/index.md)","id":"CVE-2025-48700","markdown":"https://insights.sbomify.com/CVE-2025-48700/index.md","name":"CVE-2025-48700","record":{"aliases":["GHSA-wmq6-ffv7-gqwf"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Zimbra Collaboration","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in Zimbra Classic UI via crafted emails, potentially stealing sensitive data or taking over accounts.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zimbra_collaboration_suite","vendor":"synacor"}],"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":"An issue was discovered in Zimbra Collaboration (ZCS) 8.8.15 and 9.0 and 10.0 and 10.1. A Cross-Site Scripting (XSS) vulnerability in the Zimbra Classic UI allows attackers to execute arbitrary JavaScript within the user's session, potentially leading to unauthorized access to sensitive information. This issue arises from insufficient sanitization of HTML content, specifically involving crafted tag structures and attribute values that include an @import directive and other script injection vectors. The vulnerability is triggered when a user views a crafted e-mail message in the Classic UI, requiring no additional user interaction.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":false,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Cross-site Scripting","id":"CVE-2025-48700","indexable":true,"kev":{"dateAdded":"2026-04-20","dueDate":"2026-04-23","knownRansomwareCampaignUse":"Unknown","product":"Zimbra Collaboration Suite (ZCS)","requiredAction":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.","vendorProject":"Synacor","vulnerabilityName":"Synacor Zimbra Collaboration Suite (ZCS) Cross-site Scripting Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"synacor:zimbra_collaboration_suite","products":["synacor:zimbra_collaboration_suite"],"type":"xss","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"SQL injection in openDCIM","id":"CVE-2025-48701"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2025-48699"},"products":["n/a"],"published":"2025-06-23","related":[{"cvss_score":10,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Command Execution","id":"CVE-2024-45519","kev_date_added":"2024-10-03","published":"2024-10-02"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Arbitrary File Upload","id":"CVE-2022-41352","kev_date_added":"2022-10-20","published":"2022-09-26"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Authentication Bypass","id":"CVE-2022-37042","kev_date_added":"2022-08-11","published":"2022-08-11"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Command Injection","id":"CVE-2022-27924","kev_date_added":"2022-08-04","published":"2022-04-20"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Server-Side Request Forgery","id":"CVE-2020-7796","kev_date_added":"2026-02-17","published":"2020-02-18"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Improper Restriction of XML External Entity Reference","id":"CVE-2019-9670","kev_date_added":"2022-01-10","published":"2019-05-29"},{"cvss_score":9,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Cross-Site Scripting (XSS)","id":"CVE-2023-34192","kev_date_added":"2025-02-25","published":"2023-07-06"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-21","vendors":["n/a"]},"summary":"Attackers can execute arbitrary JavaScript in Zimbra Classic UI via crafted emails, potentially stealing sensitive data or taking over accounts.","url":"https://insights.sbomify.com/CVE-2025-48700/"}
