CVE-2026-20800 fixed private-info leakage to revoked users only for the notification endpoint. Two sibling endpoints that return data keyed on the caller's own relationship still do not re-check repo access at output time:
GET /api/v1/user/starred — getStarredRepos() computes a per-repo permission but still lists every
starred repo (no filtering), so the full repo object (full_name, private, clone_url, ssh_url)
of a now-inaccessible private repo is returned.GET /api/v1/user/times — ListMyTrackedTimes() queries by UserID only and LoadAttributes brings
in the issue (title, state), leaking private issue titles after revocation.Using the provided reproduction materials, as a revoked user:
GET /api/v1/repos/admin/starred-test → 404.GET /api/v1/user/starred → leaks admin/starred-test, private:true, clone_url.GET /api/v1/user/times → leaks issue.title = "SECRET: …", state.(Runtime-confirmed on gitea/gitea:1.25.4. Oracle = planted sentinel title; no real secret exfiltrated.)
A former collaborator can enumerate private repos they starred and read private issue titles they logged time on, indefinitely after access revocation. Metadata only (no repo content / comment bodies). Low.
getStarredRepos: drop (or minimally redact) repos where permission.HasAnyUnitAccessOrPublicAccess()
is false for the caller.ListMyTrackedTimes: filter tracked-time entries by current repo access.Reported as part of an incomplete-patch measurement study (responsible disclosure).
A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.
CVSS (Common Vulnerability Scoring System) estimates technical severity, but it doesn't automatically equal business risk. Prioritize using context like internet exposure, affected asset criticality, known exploitation (proof-of-concept or in-the-wild), and whether compensating controls exist. A "Medium" CVSS on an exposed, production system can be more urgent than a "Critical" on an isolated, non-production host.
A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. In practice, risk increases sharply when exploitation becomes reliable or widespread.
Recurring findings usually come from incomplete Asset Discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host. Unknown or unmanaged assets (often called Shadow IT) are a common reason the same issues resurface.
Use a simple, repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress using consistent metrics so remediation is steady, not reactive.
SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.
