{"cve":"CVE-2026-48708","nvd":{"published":"2026-06-15T21:17:15.570","modified":"2026-06-24T17:17:01.410","status":"Deferred","description":"OliveTin gives access to predefined shell commands from a web interface. In versions 3000.0.0 and prior, the template engine uses a single shared text/template.Template instance (tpl package-level variable in service/internal/tpl/templates.go) across all goroutines. Every action execution calls tpl.Parse(source) followed by t.Execute() on this shared instance with no synchronization. When two or more actions execute concurrently (which is the normal case — each ExecRequest spawns a goroutine), a race condition occurs: one goroutine's Parse overwrites the template tree while another goroutine is calling Execute, causing cross-user command contamination, Go runtime panic, and incorrect command execution. This issue has been resolved in version 3000.13.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5},"cwes":["CWE-362","CWE-567"],"references":["https://github.com/OliveTin/OliveTin/commit/d74da9314005954dd49fa20dabf272247bc76519","https://github.com/OliveTin/OliveTin/releases/tag/3000.13.0","https://github.com/OliveTin/OliveTin/security/advisories/GHSA-7fq5-7wr8-rjwj","https://github.com/OliveTin/OliveTin/security/advisories/GHSA-7fq5-7wr8-rjwj"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:39:28.638635428+00:00"},"epss":{"cve":"CVE-2026-48708","score":0.00402,"percentile":0.34447,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7fq5-7wr8-rjwj","url":"https://osv.dev/vulnerability/GHSA-7fq5-7wr8-rjwj","summary":"OliveTin has a Concurrent Template Parsing Race Condition which Leads to Cross-Request Command Contamination","modified":"2026-07-20T21:32:33Z","packages":[{"ecosystem":"Go","name":"github.com/OliveTin/OliveTin","purl":"pkg:golang/github.com/OliveTin/OliveTin","ranges":["<0.0.0-20260521225117-d74da9314005"],"fixed":["0.0.0-20260521225117-d74da9314005"]}]},{"id":"GO-2026-5216","url":"https://osv.dev/vulnerability/GO-2026-5216","summary":"OliveTin has a Concurrent Template Parsing Race Condition which Leads to Cross-Request Command Contamination in github.com/OliveTin/OliveTin","modified":"2026-06-25T19:45:17.524971079Z","packages":[{"ecosystem":"Go","name":"github.com/OliveTin/OliveTin","purl":"pkg:golang/github.com/OliveTin/OliveTin","ranges":["<0.0.0-20260521225117-d74da9314005"],"fixed":["0.0.0-20260521225117-d74da9314005"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
