An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

The AIL Framework crawler task creation API (api_add_crawler_task) contained an insufficient authorization check when a user supplied a cookiejar UUID to attach to a one-shot or scheduled crawler task. The original code only verified that the cookiejar existed and, if its access level was 0, compared the cookiejar's owning user ID to the requesting user ID. It did not validate organizational boundaries, did not account for the requesting user's role. When the cookiejar level was not 0, no access check was performed at all. An authenticated user could therefore reference another organization's cookiejar by UUID and have the crawler use that organization's stored cookies (session tokens, authentication credentials) when performing web crawls, effectively leaking or exfiltrating the victim organization's session data.

The vulnerability requires an authenticated user with the ability to create crawler tasks. The attacker must know or guess a valid cookiejar UUID belonging to another organization. The impact is unauthorized access to another organization's stored cookies and session data through the crawler infrastructure.

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.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. 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".

The original code only verified that the cookiejar existed and, if its access level was 0,…
When was the CVE record for CVE-2026-100177 published?
The CVE record for CVE-2026-100177 was published on September 25, 2026. That is the record's publication date; the vulnerability itself may have been made public earlier. EchelonGraph's copy of the record carries a last-modified date of September 25, 2026; the record at its source may have been updated since.
Is CVE-2026-100177 actively exploited?
CVE-2026-100177 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.3% probability of exploitation in the next 30 days (27th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-100177?
CVE-2026-100177 has a CVSS base score of 6.3 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-100177?
An upstream fix for CVE-2026-100177 has been merged but is not yet in a tagged release. Until it ships, restrict network exposure of the affected system or apply the vendor's mitigation, then update to the release that contains the fix. The vendor advisories EchelonGraph has for CVE-2026-100177 are linked in the Vendor Advisories panel on this page.
