Adobe has released its October 2026 security updates addressing
174 vulnerabilities across 11 product families
, including several critical flaws that could allow attackers to execute code remotely without authentication. For Kent SMEs using Adobe software—particularly ColdFusion, Commerce (Magento), Photoshop, or Experience Manager—these patches require immediate attention to prevent potential breaches.
This update is particularly significant because
Adobe’s October 2026 security updates fix critical, high and medium vulnerabilities across eleven product families, with the most severe (several rated CVSS 10.0) in ColdFusion, Adobe Commerce/Magento and Experience Manager
. Understanding which products you run and deploying these updates quickly should be a priority for any business using Adobe software this week.
Critical Adobe Vulnerabilities Demand Urgent Patching in October 2026
The most serious flaws in this month’s release carry maximum severity ratings and affect products commonly used by UK SMEs for web development, e-commerce, and creative workflows.
Adobe ColdFusion: Three Critical Unauthenticated Flaws
ColdFusion contains 10 Critical flaws, including three unauthenticated, network-reachable bugs rated 9.8 or higher (CVE-2026-105899 rated 10.0; CVE-2026-106622 rated 10.0; CVE-2026-106624 rated 9.8), requiring updates to version 2025.0.14 or 2023.0.26
. These vulnerabilities could allow an attacker to execute arbitrary code on your server without any authentication—effectively giving them complete control of your ColdFusion application and potentially your entire web infrastructure.
If your Kent business runs ColdFusion for web applications, customer portals, or internal systems, these flaws represent an immediate and critical risk. The unauthenticated nature means attackers need no credentials whatsoever to exploit them.
Adobe Commerce and Magento: E-Commerce Platform Risks
Commerce contains five Critical flaws, including CVE-2026-103849 (rated 10.0) and CVE-2026-92909 (rated 9.8), both unauthenticated, and customers must also apply the hotfix for CVE-2026-75650 from the September 7 APSB26-146 update
. For SMEs running e-commerce sites on Adobe Commerce or Magento Open Source, these vulnerabilities could compromise customer data, payment processing, and business operations.
Note the important detail: this month’s patch alone is insufficient. You must also apply a separate September hotfix to be fully protected, adding complexity to the patching process for e-commerce businesses.
Adobe Experience Manager: Web Content Management at Risk
Adobe Experience Manager contains 33 vulnerabilities with a highest severity of Critical and CVSS score of 10.0
. Organisations using Experience Manager for web content management face significant exposure if these patches are delayed, particularly given the critical severity ratings.
Additional Adobe Products Requiring October 2026 Updates
Beyond the critical-severity products, Adobe has released security updates for eight additional products that many Kent SMEs use daily:
- Adobe Photoshop:
Adobe has released a priority 3 security update for Adobe Photoshop addressing vulnerabilities rated high and medium that could result in arbitrary code execution and application denial-of-service - Adobe Bridge: Four high-severity vulnerabilities affecting version 15.1.8 and earlier
- Adobe Dimension: Seven high-severity flaws requiring updates
- Adobe Substance 3D products: Multiple vulnerabilities across Designer, Sampler, and Stager
- Adobe FrameMaker: 10 high-severity vulnerabilities
- Content Credentials SDK: 30 vulnerabilities rated high severity
Whilst these products carry lower deployment priority ratings than ColdFusion and Commerce, the potential for arbitrary code execution means attackers could still compromise workstations running vulnerable versions, potentially gaining access to your network and sensitive creative files.
No Active Exploitation Yet—But Patching Window Is Narrow
Adobe reports no known exploits in the wild but urges urgent updating
. This creates a critical window of opportunity for Kent businesses to patch before exploit code becomes publicly available.
History shows that once vendors publish vulnerability details, attackers rapidly develop exploits. The high CVSS scores and unauthenticated nature of several October flaws make them particularly attractive targets. The absence of active exploitation today does not guarantee safety tomorrow.
This situation mirrors the Microsoft October 2026 Patch Tuesday cycle, which also included critical vulnerabilities requiring immediate attention. SMEs must develop consistent patching cadences that accommodate both Microsoft and Adobe monthly release cycles.
What Kent SMEs Using Adobe Software Must Do This Week
1. Identify All Adobe Products in Your Environment
Many businesses underestimate their Adobe footprint. Beyond obvious applications like Photoshop, check for ColdFusion web servers, Commerce/Magento e-commerce platforms, and Experience Manager installations that may be managed by different teams or external developers.
Create an inventory that includes:
- Product name and exact version number
- Server or workstation location
- Business function supported
- Person or team responsible for updates
2. Prioritise Based on Internet Exposure and Criticality
Apply patches in this order:
- Internet-facing ColdFusion, Commerce, and Experience Manager systems (critical risk, update immediately)
- Internal ColdFusion and Commerce systems (high risk, update within 48 hours)
- Desktop creative applications (medium risk, update within one week)
Internet-exposed systems with unauthenticated critical vulnerabilities represent your highest risk and should receive patches within hours, not days. Given the severity of this month’s updates, consider this comparable to the urgency described in our coverage of Google Chrome’s critical memory flaws.
3. Apply Both October Updates and September ColdFusion/Commerce Hotfixes
For ColdFusion and Adobe Commerce users,
Commerce/Magento customers must also apply the separate September 7 hotfix for CVE-2026-75650
. Missing this additional step leaves a known vulnerability unpatched despite applying October updates.
Verify that your update process includes:
- October 2026 main security update (APSB26-144 for ColdFusion, APSB26-153 for Commerce)
- September 2026 hotfix for CVE-2026-75650 (Commerce only)
- Post-update testing to confirm functionality
4. Test in Non-Production Environments First
Where possible, deploy updates to development or staging environments before production systems. This helps identify compatibility issues with custom code, third-party plugins, or integrations that could disrupt business operations.
For small businesses without separate test environments, schedule updates during low-traffic periods and ensure you have verified backups and rollback procedures ready.
5. Consider Managed Security Support
If your business lacks internal expertise to track, test, and deploy Adobe security updates consistently, professional IT support can ensure patches are applied promptly and correctly. This is particularly important for businesses running ColdFusion or Commerce platforms where vulnerabilities carry maximum severity ratings.
The complexity of managing multiple vendor patch cycles—Microsoft, Adobe, Google Chrome, and others—whilst maintaining business operations makes a strong case for outsourced patch management for many Kent SMEs. This approach complements broader security frameworks like Cyber Essentials certification, which many supply chains now require.
Adobe Moves to Twice-Monthly Security Release Schedule
An important development for patch management planning:
Adobe fixed about 140 flaws in 10 products and now ships security updates twice a month, with the company moving from monthly to twice-monthly security bulletins
. This change means businesses must adjust their patching cadences to accommodate more frequent Adobe releases.
For SMEs already struggling with the volume of security updates from multiple vendors, this acceleration presents both challenges and opportunities. More frequent, smaller updates may be easier to test and deploy than large monthly releases, but they also require more consistent attention to security bulletins.
Protect Your Kent Business from Adobe Software Vulnerabilities
The October 2026 Adobe security updates include some of the most severe vulnerabilities Adobe has published this year, with multiple CVSS 10.0 critical flaws affecting commonly used products. For Kent SMEs running ColdFusion web applications, Commerce e-commerce platforms, or creative software suites, immediate patching is essential to prevent potential breaches.
The combination of maximum severity scores, unauthenticated exploitation paths, and internet-facing deployment scenarios creates significant risk for businesses that delay these updates. Whilst Adobe reports no active exploitation yet, the publication of vulnerability details and proof-of-concept code typically follows vendor patches by days or weeks, creating a narrow window for protection.
