PinchTab v0.8.3…","summary":"PinchTab v0.8.3 contains a server-side request forgery issue in the optional scheduler's webhook delivery path. When a task submitted to POST /tasks has a user-controlled callbackUrl, the server sends an outbound POST to that URL without rejecting loopback or private destinations, and it follows redirects, enabling blind SSRF toward attacker-chosen targets reachable from the server. The scheduler is off by default, and in token-protected deployments the attacker must already hold the master API token.","solution":"Fixed in v0.8.4, which validates callback targets before dispatch, rejects non-public IP ranges, pins delivery to validated IPs, disables redirect following, and validates callbackUrl during task submission.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-33619","publishedAt":"2026-03-26T21:17:06.220Z","cveId":"CVE-2026-33619","cweIds":["CWE-918"],"cvssScore":"4.1","cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":["github.com/pinchtab/pinchtab@<= 0.8.3 (fixed: 0.8.4)"],"affectedPackageNames":["github.com/pinchtab/pinchtab"],"affectedPackageRefs":["go:github.com/pinchtab/pinchtab"],"affectedVendors":[],"affectedVendorsRaw":["PinchTab"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"PinchTab server-side request forgery in scheduler webhook delivery","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:L/A:N","attackVector":"network","attackComplexity":"low","privilegesRequired":"high","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00258,"epssCheckedAt":"2026-11-11T06:13:02.403Z","kevDateAdded":null,"advisoryAliases":["GHSA-xqq2-4j46-vwp7"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:50:15.186Z","patchAvailable":true,"disclosureDate":"2026-03-26T21:17:06.220Z","fixReleasedAt":"2026-03-19T01:58:04.000Z","daysToFix":-7,"fixCheckedAt":"2026-10-29T21:39:31.945Z","capecIds":["CAPEC-664"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"go","name":"github.com/pinchtab/pinchtab","fixedVersion":"0.8.4","matchedVersion":"v0.8.4","fixReleasedAt":"2026-03-19T01:58:04.000Z","daysToFix":-7,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:39:31.799Z"}]}}
