Adobe Patches Over 170 Vulnerabilities, Including Commerce Zero-Day

CVE-2026-48273 is a critical (CVSS 9.9) eval injection flaw (CWE-95) in Adobe ColdFusion in which untrusted input is not properly neutralized before it is placed into dynamically evaluated code. A remote attacker who has only low-privileged access to a vulnerable ColdFusion server can trigger the flaw over the network, with no user interaction required. Successful exploitation yields arbitrary code execution in the context of the current user, and the changed CVSS scope (S:C) indicates the impact can extend beyond the directly vulnerable component, a pattern typical of ColdFusion flaws that enable broader system-level code execution. All Adobe ColdFusion deployments are potentially affected; the source data does not specify affected version ranges, so admins should consult Adobe's bulletin for the exact versions fixed. As of this writing there is no known public proof-of-concept and the flaw is not in CISA KEV, though EPSS assigns a 1.7% probability of exploitation within 30 days; the fix shipped in Adobe's large recent patch batch, which also addressed three CVSS 10.0 ColdFusion and Campaign Classic flaws.

Do: Apply the Adobe ColdFusion security update covering this CVE from the current patch batch immediately on all ColdFusion servers, prioritizing any that are internet-exposed, and confirm your exact version against Adobe's bulletin since fixed versions are not listed here. Because only low-privileged access is required and no user interaction is needed, audit which accounts and request paths feed untrusted input into dynamically evaluated expressions and restrict or validate such inputs. No public PoC or known exploitation exists yet, so monitor Adobe advisories and threat feeds for updated indicators of compromise.

Adobe Commerce and Magento (including Adobe Commerce B2B) contain an improper neutralization of special elements used in a template engine (CWE-1336), a template-injection flaw that permits arbitrary code execution in the context of the current user. The flaw is reachable over the network by unauthenticated attackers, requires no user interaction, and its changed scope (CVSS 3.1 S:C) means injected code executes beyond the vulnerable component, producing a maximum-severity (CVSS 10.0) remote code execution condition. A successful attacker gains arbitrary code execution on the storefront server; in the observed campaign, intruders installed a Rust backdoor and a PHP web shell (dubbed 'StyleSmuggler') on compromised servers. Any organization running an Adobe Commerce, Adobe Commerce B2B, or Magento storefront is in scope, with internet-facing e-commerce deployments most exposed. Exploitation is confirmed in the wild: the bug was abused as a zero-day before patching and was added to CISA's Known Exploited Vulnerabilities catalog on 2026-09-08.

Do: Apply Adobe's released patches immediately per vendor instructions, prioritizing internet-facing Commerce/Magento storefronts, and ensure compliance with CISA BOD 26-04 timelines for KEV entries. Hunt for 'StyleSmuggler' indicators of compromise, including unexpected Rust backdoor binaries and PHP web shells on hosts, and review template/theme customizations for tampering. Exact fixed version numbers are not included in the available data, so consult Adobe's advisory for the correct patched release for your Commerce/Magento version line.

CVE-2026-75746 is an SQL injection flaw (CWE-89) in Adobe ColdFusion that can escalate to arbitrary code execution in the context of the current user. A remote attacker who has already obtained high-privileged access, such as administrative-level credentials, can trigger the flaw over the network without any user interaction, and the changed scope means the impact extends beyond the vulnerable component's normal security boundary. Successful exploitation carries high-impact confidentiality, integrity, and availability consequences for the server. Organizations running Adobe ColdFusion, particularly internet-facing instances or deployments where privileged access is reachable by less-trusted users, are in scope. As of this analysis there is no public proof-of-concept, the flaw is not in CISA KEV, and EPSS estimates roughly a 1.1% chance of exploitation within 30 days, indicating no known exploitation to date.

Do: Apply the ColdFusion security update issued in Adobe's recent batch (which patched over 170 vulnerabilities) and confirm your installed build matches the fixed release listed in the Adobe advisory. Because the flaw requires high-privileged access, restrict administrative access to ColdFusion, rotate and harden privileged credentials, review logs for unexpected SQL activity from privileged accounts, and limit internet exposure of the server. No public PoC or KEV listing exists yet, but prioritize patching internet-facing ColdFusion instances given the critical base score.

Adobe Campaign Classic (ACC) contains an OS command injection flaw (CWE-78) in which special elements passed to an operating system command are improperly neutralized, allowing attacker-supplied commands to run on the host. Per the CVSS vector, it is reachable over the network (AV:N), requires no privileges or user interaction, and has changed scope (S:C), meaning a successful attack can also affect resources beyond the vulnerable component. An attacker gains arbitrary code execution in the context of the current user, with high impact to confidentiality, integrity, and availability. Any organization running an affected Adobe Campaign Classic deployment is potentially exposed, though only instances reachable over the network are practically exploitable. No public proof-of-concept or confirmed in-the-wild exploitation is known, EPSS estimates a ~1.4% probability of exploitation within 30 days, and the fix arrived in a large Adobe patch release covering 170+ vulnerabilities.

Do: Upgrade Campaign Classic to the fixed build listed in Adobe's security bulletin for this CVE, since the affected and fixed version numbers are not included in the data provided. Until patched, limit network exposure of Campaign Classic application/web servers to trusted networks, as the flaw is exploitable without authentication or user interaction. Monitor for a public PoC or CISA KEV listing and review application service accounts for signs of unexpected command execution.
