MITRE ATT&CK
2 techniques across 2 tactics: Initial Access, Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Adobe Connect versions 2025.3, 12.10 and earlier. Requires low-privilege authenticated attacker account. Victim must click malicious URL or visit compromised web page in their browser session. Scope change enables privilege escalation. |
| Impact | Real-world risk is moderate-to-high despite the 8.7 CVSS score. The attack vector is network-based with low complexity (AV:N/AC:L), enabling remote exploitation, but mandatory user interaction (UI:R) creates a significant barrier requiring social engineering success. The changed scope (S:C) and high confidentiality/integrity impact (C:H/I:H) elevate concern for multi-tenant environments where privilege escalation could compromise administrative functions or multiple user sessions. EPSS probability not available in provided data, limiting automated risk quantification. No CISA KEV listing and no public exploit code suggest this is not yet actively weaponized, but Adobe's security bulletin publication makes this exploitable by moderately skilled attackers. SSVC framework considerations: exploitation status is public (CVE disclosed), automatable is 'no' (requires user interaction), technical impact is total (privilege escalation with changed scope). Priority should be high for organizations using Adobe Connect in shared hosting or multi-tenant configurations, moderate for isolated deployments with limited user bases. |
| Exploit ScenarioDerived | A low-privileged authenticated Adobe Connect user crafts a malicious URL containing JavaScript payloads targeting session cookies or authentication tokens. The attacker shares this URL through Adobe Connect's chat, shared notes, or meeting invitation features, enticing a meeting host or administrator to click. When the victim accesses the URL within their authenticated Adobe Connect session, the injected script executes with the victim's privileges, exfiltrating session credentials or performing administrative actions such as modifying user permissions, accessing confidential meeting recordings, or injecting persistent backdoors into shared content repositories accessible across the changed scope boundary. |

Alert meAnalysisAIv1 – Apr 14, 2026
Cross-site scripting (XSS) in Adobe Connect versions 12.10 and earlier, including the 2025.3 release line, enables privilege escalation when low-privileged authenticated users trick victims into visiting malicious URLs. The changed scope (CVSS S:C) indicates the vulnerability can affect resources beyond the vulnerable application's security context. EPSS data not available; no evidence of active exploitation (not in CISA KEV) or public exploit code at time of analysis. Requires user interaction (UI:R) but has low attack complexity (AC:L) and network-based attack vector (AV:N), making social engineering campaigns feasible.
RemediationAI
Adobe has released security bulletin APSB26-37 addressing this vulnerability. Organizations must immediately apply the vendor-provided patch by upgrading to the version specified in the advisory at https://helpx.adobe.com/security/products/connect/apsb26-37.html (exact patched version number not provided in available data; consult bulletin directly). As an interim control while planning upgrades, implement strict Content Security Policy (CSP) headers to mitigate XSS injection effectiveness, restrict low-privileged user capabilities to share URLs or embed content in meeting rooms, and educate users to avoid clicking unverified links within Adobe Connect sessions. Monitor authentication logs for unusual privilege escalation patterns or session hijacking indicators. Prioritize patching for internet-facing deployments and environments where untrusted low-privileged users can interact with high-privilege accounts.

Technical ContextAI · show details
This vulnerability manifests in Adobe Connect's web conferencing platform (CPE: cpe:2.3:a:adobe:adobe_connect), stemming from CWE-79 (Improper Neutralization of Input During Web Page Generation). XSS flaws occur when user-supplied data is reflected in HTML responses without adequate sanitization or encoding. In this case, the changed scope indicator (S:C in CVSS vector) suggests the injected scripts can breach the trust boundary between Adobe Connect and other components, potentially accessing session tokens, cookies, or resources in connected Adobe services. The PR:L (low privileges required) designation indicates authenticated users with minimal permissions can craft the attack payload, likely targeting higher-privileged administrators or meeting hosts who interact with shared content, URLs, or collaborative features within the platform.

DescriptionCVE.org
Adobe Connect versions 2025.3, 12.10 and earlier are affected by a Cross-Site Scripting (XSS) vulnerability that could result in privilege escalation. A low-privileged attacker could exploit this vulnerability to inject malicious scripts into a web page, potentially gaining elevated access or control over the victim's account or session. Exploitation of this issue requires user interaction in that a victim must visit a maliciously crafted URL or interact with a compromised web page. Scope is changed.
Executive ViewAI
Adobe Connect versions 12.10 and earlier contain a stored cross-site scripting vulnerability that allows authenticated users to escalate privileges and compromise other users' sessions through malicious URLs, posing a significant risk to organizations using this conferencing platform for sensitive communications. The attack requires social engineering but can affect resources beyond the application itself, potentially exposing connected systems and data.
No vendor-released patch identified at time of analysis. Interim mitigations: (1) Deploy Web Application Firewall rules to detect and block XSS payloads in Connect parameters; (2) Restrict low-privileged user permissions to prevent privilege escalation through application controls; (3) Implement Content Security Policy (CSP) headers to limit script execution scope; (4) Monitor for suspicious URL sharing and privilege elevation events in audit logs; (5) Conduct user awareness training on phishing and malicious link risks specific to conferencing platforms.

Attack Technique
Cross-Site Scripting occurs when an application accepts untrusted data and sends it to a web browser without proper validation or encoding.
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
