Lifecycle Timeline
2DescriptionCVE.org
Adobe Experience Manager is affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low-privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim's browser when they browse to the page containing the vulnerable field. Scope is changed.
AnalysisAI
Stored Cross-Site Scripting in Adobe Experience Manager allows low-privileged authenticated attackers to inject persistent malicious JavaScript into vulnerable form fields. When any user - including administrators - browses to pages containing the poisoned fields, the injected script executes in their browser under the AEM origin, enabling session token theft, credential harvesting, or UI redirection. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Attacker must hold a valid low-privileged AEM account (such as a content-author or contributor role) with write access to at least one form field that is stored and later rendered to other users without output encoding. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.4 (Medium) score with vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N is consistent with a realistic stored XSS: network-reachable, low attack complexity once an account exists, but requiring a low-privileged account and passive victim interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult and apply the guidance in Adobe Security Bulletin APSB26-98 at https://helpx.adobe.com/security/products/experience-manager/apsb26-98.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
