Exploitation Conditions

Exploitation requires a valid authenticated account on the IBM Security Verify Access / Verify Identity Access Web UI (PR:L) with the ability to submit input into a Web UI field that is rendered back without sanitization, plus a second user loading that content for the injected JavaScript to execute (UI:R). The scope-changing impact (S:C) means the payload runs in a victim's trusted session, enabling credential/session disclosure. Limiting factors: attacker must already be authenticated, exploitation is not automatic because it depends on victim interaction, and impact is confined to data accessible within the victim's session (no availability impact). Affects SVA 10.0 through 10.0.9.2 and VIA 11.0 through 11.0.3, including the container editions, per the CPE list.

Impact

This is a moderate-severity stored/reflected cross-site scripting issue (CVSS 5.4) rather than a top-priority emergency. The CVSS vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) tells a consistent story with the description: network-reachable but requiring an authenticated user (PR:L) and victim interaction (UI:R), with only low confidentiality and integrity impact and no availability impact. The scope change (S:C) reflects that injected script executes in another user's trusted browser session, which is what raises this above a trivial self-XSS. No EPSS score, CISA KEV listing, POC, or SSVC decision data was supplied in the input, so there is no public exploit identified at time of analysis and no evidence of active exploitation - the automatable and exploitation-maturity signals of SSVC cannot be evaluated from available data. The combination of required authentication plus required user interaction materially limits real-world risk, so despite the network attack vector this is better treated as a standard patch-cycle item than an urgent out-of-band fix, prioritized higher only in multi-tenant or shared-administration deployments where one authenticated user can reach another's session.

Exploit ScenarioDerived

An authenticated user with access to the Verify Access/Verify Identity Access Web UI submits input containing arbitrary JavaScript into a field that is later rendered without proper sanitization. When another authenticated user (e.g., an administrator) views the affected page, the script executes in their trusted session, potentially harvesting session credentials or performing actions as that victim. No public exploit code was identified in the provided data, and success depends on the victim loading the malicious content (UI:R).

AnalysisAIv1 – Oct 08, 2026

Cross-site scripting in the IBM Security Verify Access (10.0 through 10.0.9.2) and IBM Verify Identity Access (11.0 through 11.0.3) Web UI allows an authenticated user to embed arbitrary JavaScript into a field that is later rendered to another user, so the payload executes within that victim's trusted session (scope change, S:C) and can lead to credential or session disclosure. The CVSS vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, score 5.4) confirms remote reachability but requires a valid low-privileged account plus victim interaction; there is no availability impact and the exposure is limited to data reachable inside the victim's session. No public exploit code exists and there is no confirmed active exploitation (CISA KEV) at the time of analysis; a vendor patch is available per the IBM advisory.

RemediationAI

Patch status per the vendor: patch available per vendor advisory - IBM has published remediation guidance for CVE-2026-78407 at https://www.ibm.com/support/pages/node/7291628, and the supported resolution is to upgrade Security Verify Access (10.0.x) and Verify Identity Access (11.0.x), including the corresponding container images, to the fixed level specified in that advisory, since the input data does not provide a discrete fix version and none should be assumed. Where immediate upgrade is not possible, compensating controls should target the three prerequisites of the attack: because the attacker must be authenticated (PR:L), audit and minimize the number of accounts that can write into Web UI fields and remove or disable unused/high-privilege accounts, though this reduces the attack surface rather than eliminating the flaw; because exploitation depends on a victim loading the injected content (UI:R), administrators should avoid following untrusted links into the Verify Access console and can tighten the deployment with a Content Security Policy that disallows inline and third-party script on the admin interface, accepting the risk that a restrictive CSP may break legitimate UI behavior and must be tested before enforcement; and because the impact is session-scoped credential disclosure (S:C/C:L), enforce short session lifetimes, re-authentication for sensitive actions and session-binding checks so that any stolen session token has limited value, with the trade-off of added user friction. Monitoring for anomalous JavaScript-bearing input and unexpected console access patterns provides detection while remediation is staged, and all mitigations should be validated against the vendor advisory before being treated as equivalent to patching.

Technical ContextAI · show details

The flaw is a cross-site scripting (XSS) condition in the web-based administration/user interface of IBM Security Verify Access and IBM Verify Identity Access, including their container editions (per the supplied CPEs: security_verify_access, verify_identity_access, security_verify_access_container, verify_identity_access_container). While the input did not include an explicit CWE, the described behavior - an authenticated user supplying arbitrary JavaScript that is stored or reflected into the Web UI and executed in a second user's browser - is the classic improper neutralization of user-controllable input during web page generation (CWE-79) class. The CVSS vector is the key technical signal: PR:L indicates the attacker must already hold a valid, low-privileged account; UI:R indicates the victim must load or interact with the crafted content before script executes; and S:C indicates the injected code runs in the security context of the vulnerable Web UI origin rather than the attacker's, which is what makes disclosure of credentials or session material inside a trusted session possible. AC:L means no special conditions beyond the above are required, and C:L/I:L with A:N caps the effect at partial confidentiality and integrity loss confined to what the victim's session can reach. Because the payload runs in the victim's browser context against a trusted IBM interface, standard single-origin defenses do not stop it once the injection point exists; the fix must be server-side output encoding/sanitization in the vulnerable UI components.
