EchelonGraph scoreHIGH confidence

“▲” beside the score: it is higher than the CVSS score beside it.

Score elevated to 9.0 because this CVE is listed on ENISA's EU Known Exploited Vulnerabilities catalogue (Source: ENISA EUVD), indicating that ENISA records real-world exploitation of it. It is not on CISA's Known Exploited Vulnerabilities catalog. CISA-ADP (Vulnrichment) CVSS v3.1 baseline 7.5 retained for reference (NVD's own analysis pending). The 9.0 is the floor for confirmed exploitation, not an impact rating: this CVE's impact severity (EG Severity) is CVSS 7.5 HIGH under GitHub Security Advisory CVSS. Confidence: HIGH.

EG Risk
89
EG Risk 89/100

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.

How it’s computed (value × EchelonGraph’s weight)

Exploitation active (ENISA EU KEV listing; Source: ENISA EUVD) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). From CISA's SSVC values (Vulnrichment): automatable and technical impact; the others come from the sources named beside them. EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE.
Action: No fix is confirmed yet. Check the vendor's advisory for a fixed release; until one is applied, restrict network exposure of the affected system or apply the vendor's mitigation sooner than your normal schedule at low or medium mission impact and as soon as possible at high.

SSVC (CISA's decision table, applied by EchelonGraph)Attend at low or medium mission impact; Act at high (mission-essential systems).

No fix is confirmed yet. Check the vendor's advisory for a fixed release; until one is applied, restrict network exposure of the affected system or apply the vendor's mitigation sooner than your normal schedule at low or medium mission impact and as soon as possible at high.

Exploitation active (ENISA EU KEV listing; Source: ENISA EUVD) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). From CISA's SSVC values (Vulnrichment): automatable and technical impact; the others come from the sources named beside them. 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".

No released fix is confirmed on this page, but CISA's timeline does not wait for a fix's release: it starts when an agency identifies the flaw on an asset and updates the CDM Agency and Federal Dashboard, and the directive counts patching, decommissioning the system or another action as remediation. Until a fixed release is applied, mitigate as this page's verdict says.

Data Freshness Timeline

(refreshed 14× in last 7d / 53× 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 its CVE.org record (CNA or CISA ADP). 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). "EchelonGraph re-scored" is our own recompute of this CVE's score, not an update from a source, and is not counted in the refreshes above. Most recent first.

Showing the most recent 100 of 295 rows on record for this CVE.

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. None are among the latest 100 rows. The 195 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Publicly available exploits

(3 references)

Public exploit code is referenced for this CVE (1 GitHub PoC), as are 1 Nuclei detection template, 1 GitHub checker repository. A detection template checks whether a system is affected; it is not necessarily exploit code. A GitHub repository named or described as a checker or scanner checks whether a system is affected; it is not necessarily exploit code. No fix is confirmed yet, so defenders should restrict or isolate affected systems accordingly until one is published.

Frequently asked(5)

What is CVE-2026-49049?
CVE-2026-49049 is a critical-severity vulnerability; its CVE record was published on June 29, 2026. The Helix3 plugin for Joomla exposes an ajax handler task, that allows unauthenticated attackers to delete arbitrary files, write arbitrary JSON files and update template parameters.
When was the CVE record for CVE-2026-49049 published?
The CVE record for CVE-2026-49049 was published on June 29, 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 October 25, 2026; the record at its source may have been updated since.
Is CVE-2026-49049 actively exploited?
CVE-2026-49049 is not currently on CISA's Known Exploited Vulnerabilities catalog. ENISA's EU Known Exploited Vulnerabilities catalogue lists CVE-2026-49049 (added July 10, 2026, reported by CERT-EE, CERT-PL): ENISA records its exploitation in the wild. Source: ENISA EUVD (EU Known Exploited Vulnerabilities catalogue), reproduced with acknowledgement. FIRST EPSS estimates a 1.0% probability of exploitation in the next 30 days (63rd percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-49049?
CVE-2026-49049 has a CVSS v3.1 base score of 7.5 (CISA-ADP / Vulnrichment enrichment; NVD's own analysis pending). EchelonGraph synthesises CISA-ADP (Vulnrichment) CVSS v3.1 + ENISA's EU KEV (Source: ENISA EUVD) + FIRST EPSS + GHSA into a combined EG score of 9.0 (CRITICAL).
How do I remediate CVE-2026-49049?
No fix for CVE-2026-49049 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 vendor advisories EchelonGraph has for CVE-2026-49049 are linked in the Vendor Advisories panel on this page.
