No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The CVE record's CNA (VulnCheck) lists pydio cells versions 5.0.0 up to and including 5.0.2 as affected. No release containing a fix is confirmed on record.

Pydio Cells 5.0.0 through 5.0.2 returns share-link details to any authenticated user. The REST handler for GET /a/share/link/{Uuid} in idm/share/rest/handler.go reads the workspace UUID from the path, calls LinkById, and writes the result with no authorization step, whereas the sibling handler for GET /a/share/cell/{Uuid} loads the workspace and requires MatchPolicies with ResourcePolicyAction_READ, returning a not-found error so that existence is not disclosed. Nothing compensates further down: GetLinkWorkspace reaches GetOrCreateWorkspace, which issues SearchWorkspace with a query carrying no ResourcePolicyQuery, and PrepareResourcePolicyQuery returns the query unmodified when that field is nil, so the workspace service applies no policy filter. The workspace UUID is not secret, because the unauthenticated public page served for a share link embeds it as START_REPOSITORY. Any account holding a standard user role can therefore submit the UUID and receive the link hash and URL, the owner's user identifier, the hidden share user login, the permission set, the download limit and count, the target users, the expiry, and the password-required flag, while a direct read of the shared node from the same account is refused.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Frequently asked(5)

What is CVE-2026-76032?
CVE-2026-76032 is a medium-severity vulnerability; its CVE record was published on August 18, 2026. Pydio Cells 5.0.0 through 5.0.2 returns share-link details to any authenticated user. The REST handler for GET /a/share/link/{Uuid} in idm/share/rest/handler.go reads the workspace UUID from the path, calls LinkById, and writes the result with no authorization step, whereas the sibling handler for…
When was CVE-2026-76032 made public?
CVE-2026-76032 was made public on August 17, 2026: that is the date its CVE record's CNA, VulnCheck, gives for when the vulnerability was made public. The CVE record itself was published on August 18, 2026. EchelonGraph's copy of the record carries a last-modified date of October 22, 2026; the record at its source may have been updated since.
Is CVE-2026-76032 actively exploited?
CVE-2026-76032 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.4% probability of exploitation in the next 30 days (31st percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-76032?
CVE-2026-76032 has a CVSS base score of 4.3 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-76032?
No fix for CVE-2026-76032 is confirmed yet. Until one is published, restrict network exposure of the affected system or apply the vendor's mitigation — for example, keep it off the internet or limit it to trusted networks — and watch the vendor's advisory for the fix. The CVE record's CNA (VulnCheck) lists pydio cells versions 5.0.0 up to and including 5.0.2 as affected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-76032 are linked in the Vendor Advisories panel on this page.
