The CVE record names the fixed release — apply it.

SigNoz versions from v0.98.0 up to (but not including) v0.143.0, when configured to use the opaque session tokenizer (which was not the default before v0.143.0), do not revoke a user's existing login sessions when the user's password is reset with a reset token (UpdatePasswordByResetPasswordToken, reachable via POST /api/v2/factor_password/reset) or when the user is deleted (DeleteUser, reachable via DELETE /api/v2/users/{id}). Neither code path calls the tokenizer's DeleteTokensByUserID, so cached tokens and identities are left in place. An attacker who already holds a session token for the account — for example from a stolen browser session or from a user being offboarded — retains the account's full access, up to administrator, after a password reset until the token reaches its configured maximum lifetime (30 days by default), and after user deletion until the token next rotates (30 minutes by default). This defeats password reset and user deletion as a means of terminating access. The issue is fixed in v0.143.0.

EG Risk 47/100

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.

SSVC (CISA's decision table, applied by EchelonGraph)Track at low, Track* at medium and Attend at high mission impact.

The CVE record names the fixed release. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (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 score's inputs: In CISA KEV no (CISA's KEV catalog) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Whether your system is publicly exposed is yours to answer. BOD 26-04 binds US Federal Civilian Executive Branch agencies; for anyone else it is CISA's published timeline, a reference rather than an obligation. The directive · how EchelonGraph applies it

(refreshed 7× in last 7d / 57× in last 30d)

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.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 1 repeat row among the latest 90 is merged into the row it repeats.

Frequently asked(5)

What is CVE-2026-97056?
CVE-2026-97056 is a medium-severity vulnerability; its CVE record was published on September 24, 2026. SigNoz versions from v0.98.0 up to (but not including) v0.143.0, when configured to use the opaque session tokenizer (which was not the default before v0.143.0), do not revoke a user's existing login sessions when the user's password is reset with a reset token (UpdatePasswordByResetPasswordToken,…
When was CVE-2026-97056 made public?
CVE-2026-97056 was made public on September 23, 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 September 24, 2026. EchelonGraph's copy of the record carries a last-modified date of September 24, 2026; the record at its source may have been updated since.
Is CVE-2026-97056 actively exploited?
CVE-2026-97056 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.4% probability of exploitation in the next 30 days (37th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-97056?
CVE-2026-97056 has a CVSS base score of 6.8 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-97056?
The CVE record for CVE-2026-97056 names the fix: "The issue is fixed in v0.143.0." The vendor advisories EchelonGraph has for CVE-2026-97056 are linked in the Vendor Advisories panel on this page.
