KEV Lag Tracker → CVE-2026-48282. Data verified against the official CISA KEV catalog and the National Vulnerability Database.
CISA added CVE-2026-48282 (Adobe ColdFusion) to the Known Exploited Vulnerabilities catalog on July 7, 2026. It was publicly known for 7 days before CISA confirmed active exploitation. A KEV listing is CISA’s official confirmation that a vulnerability is being exploited in the wild.
The Record

Measured against the 1674 entries in our tracker with verified publication dates, CVE-2026-48282 was flagged faster than 76% of them.
What CISA Reported
CISA describes the flaw as follows: “Adobe ColdFusion contains a path traversal vulnerability that could lead to arbitrary code execution in the context of the current user.”
Federal Patch Deadline
Under Binding Operational Directive rules, U.S. federal agencies must remediate CVE-2026-48282 by July 10, 2026 — a 3-day remediation window from the KEV listing date. Private organizations are not bound by that deadline; CISA treats it as the benchmark for how urgently a confirmed-exploited flaw should be patched.
What EPSS Forecast Before the Confirmation
The EPSS forecast (FIRST’s daily estimate of the probability a CVE will be exploited within 30 days) put CVE-2026-48282 at 1.02% on the day before CISA confirmed active exploitation — the 59.2% percentile of all scored CVEs that day. That places it outside the top 10% of EPSS risk on the eve of confirmation — a patch queue ordered by EPSS alone would have left it for later.
| EPSS for CVE-2026-48282 | Value |
|---|---|
| Probability the day before the KEV listing | 1.02% |
| Percentile the day before the KEV listing | 59.2% |
| Probability today (August 24, 2026) | 42.39% |
| Percentile today | 98.6% |
Today’s figure is not evidence that the forecast worked: EPSS reacts to the KEV listing itself, so the score for any confirmed-exploited CVE tends to rise after CISA acts. Only the eve-of-listing number was available to a defender making the call. Across every KEV entry we track, we measured how often that number was high — see the EPSS accuracy analysis.
How This Compares to Adobe’s Track Record
At 7 days, CVE-2026-48282 was flagged faster than Adobe’s 2632-day median across the 80 of its KEV entries with verified publication dates. Adobe currently ranks #2 on our KEV Lag leaderboard.
| Adobe in the CISA KEV catalog | Value |
|---|---|
| Tracked KEV entries | 80 |
| Median lag (public → KEV listing) | 2632 days |
| 0-day rate (exploited at or before disclosure) | 4% |
| Entries tied to known ransomware campaigns | 10 |

Frequently Asked Questions
What is CVE-2026-48282?
CVE-2026-48282 is a vulnerability in Adobe ColdFusion (Adobe ColdFusion Path Traversal Vulnerability) that CISA added to its Known Exploited Vulnerabilities catalog on July 7, 2026. A KEV listing is CISA’s official confirmation that the flaw is being exploited in the wild.
How long was CVE-2026-48282 public before CISA confirmed exploitation?
7 calendar days, measured from its NVD publication date to the date CISA added it to the KEV catalog.
What is the federal patch deadline for CVE-2026-48282?
U.S. federal agencies must remediate CVE-2026-48282 by July 10, 2026, a 3-day window from the KEV listing date. Private organizations are not bound by that deadline, but CISA treats it as the benchmark for how urgently a confirmed-exploited flaw should be patched.
Is CVE-2026-48282 used in ransomware campaigns?
CISA has not flagged CVE-2026-48282 as known to be used in ransomware campaigns. That field reflects confirmed campaign use, not the absence of risk.
What was the EPSS score for CVE-2026-48282 before it was confirmed as exploited?
1.02% — the probability EPSS assigned on the day before CISA added CVE-2026-48282 to the KEV catalog, placing it in the 59.2% percentile of all scored CVEs that day. That is outside the top 10% of EPSS risk. Its score today is higher in most cases because EPSS reacts to the KEV listing itself, so only the eve-of-listing figure reflects what a defender could have acted on.
How does this compare to other Adobe vulnerabilities?
Across 80 Adobe entries with verified publication dates, the median lag is 2632 days and 4% were exploited at or before disclosure. CVE-2026-48282, at 7 days, is faster than that median.

How We Track This
This page is generated from our CISA KEV Lag Tracker, which syncs the official CISA KEV catalog daily and records the date each CVE is added. For every entry we retrieve the original NVD publication date and compute the lag in calendar days. No date or figure on this page is estimated or taken from a third-party source — they come directly from CISA and NVD records. Free to cite with attribution to CVEDaily (CC BY 4.0).
