Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-56748 in the wild and no public exploit code.\n\nAffected product: Cribl Stream. 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-2026-56748/ (Markdown: https://insights.sbomify.com/CVE-2026-56748/index.md)","id":"CVE-2026-56748","markdown":"https://insights.sbomify.com/CVE-2026-56748/index.md","name":"CVE-2026-56748","record":{"aliases":["GHSA-xj69-cqwc-2w67"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cribl Stream","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary code via symlink following in Cribl Stream's Git import feature.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Cribl","cpe":[{"product":"cribl_stream","vendor":"cribl"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-61","name":"UNIX Symbolic Link (Symlink) Following"}],"description":"Improper validation of symbolic links in the Pack Git import feature in Cribl Stream before 4.18.2 allows a remote authenticated attacker with Pack import and pipeline preview permissions to execute arbitrary code as the Cribl server process via a crafted Git repository containing a symbolic link in the pack's functions directory.","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":"Authenticated RCE via Symlink Following in Cribl Stream Pack Git Import","id":"CVE-2026-56748","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Gitea Remember-Me Token Theft Not Invalidating Attacker Session","id":"CVE-2026-56750"},"packages":[],"prev":{"headline":"Code Injection in JSON Pointer Processing Component in Cribl Stream","id":"CVE-2026-56747"},"products":["Cribl Stream"],"published":"2026-07-27","related":[{"cvss_score":8.7,"headline":"Code Injection in JSON Pointer Processing Component in Cribl Stream","id":"CVE-2026-56747","kev_date_added":null,"published":"2026-07-27"}],"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":"total"},"state":"PUBLISHED","updated":"2026-07-27","vendors":["Cribl"]},"summary":"Authenticated attackers can execute arbitrary code via symlink following in Cribl Stream's Git import feature.","url":"https://insights.sbomify.com/CVE-2026-56748/"}
