Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Apply SAP-provided patches or updates as soon as they become available to address CVE-2026-0505. 2. Implement strict input validation and output encoding on all URL parameters within BSP applications to prevent unvalidated redirection. 3. Employ web application firewalls (WAFs) with rules designed to detect and block suspicious URL redirection patterns. 4. Restrict direct internet exposure of SAP Document Management System interfaces; use VPNs or secure gateways to limit access. 5. Conduct user awareness training focused on recognizing phishing attempts and suspicious redirects. 6. Monitor logs for unusual redirection activities or access patterns indicative of exploitation attempts. 7. Review and harden SAP system configurations to minimize unnecessary exposure of BSP applications. 8. Use Content Security Policy (CSP) headers to reduce the risk of client-side script exploitation. 9. Regularly audit and update URL parameter handling in custom BSP applications or extensions. 10. Coordinate with SAP support and security advisories to stay informed about patches and emerging threats.

Description

CVE-2026-0505 is a medium severity vulnerability in SAP Document Management System's BSP applications that allows unauthenticated attackers to manipulate URL parameters insufficiently validated, resulting in unvalidated redirection to attacker-controlled sites. This vulnerability stems from improper neutralization of input (CWE-79) and can impact confidentiality and integrity with no effect on availability. Exploitation requires user interaction but no authentication, and the vulnerability affects multiple SAP_APPL and S4CORE versions widely used in enterprise environments. While no known exploits are currently in the wild, the vulnerability's scope and ease of exploitation necessitate prompt mitigation. European organizations using affected SAP versions should prioritize patching and implement strict URL validation and monitoring to prevent phishing and redirection attacks. Countries with significant SAP deployments and critical infrastructure reliance on SAP systems are at higher risk. The CVSS score of 6.1 reflects a medium severity level due to the limited impact and required user interaction.

Impact

For European organizations, the impact primarily involves potential confidentiality and integrity breaches through phishing or malicious redirection attacks. Attackers could exploit this vulnerability to redirect users to fraudulent websites to harvest credentials or deliver malware, potentially compromising sensitive corporate or customer data. Although availability is unaffected, the reputational damage and operational disruptions from successful phishing campaigns could be significant. Organizations relying heavily on SAP Document Management System for document workflows and business processes may face increased risk of targeted social engineering attacks. The vulnerability's unauthenticated nature and network accessibility increase the attack surface, especially in environments where SAP systems are exposed to the internet or insufficiently segmented. Given SAP's widespread use in European industries such as manufacturing, finance, and public sector, the threat could affect critical infrastructure and business continuity if exploited in conjunction with other attack vectors.

Summary

CVE-2026-0505 is a vulnerability identified in the SAP Document Management System, specifically within BSP (Business Server Pages) applications. The root cause is improper neutralization of input during web page generation, classified under CWE-79 (Cross-Site Scripting). The vulnerability allows unauthenticated attackers to manipulate user-controlled URL parameters that are not sufficiently validated or sanitized. This manipulation can lead to unvalidated redirection, where victims are redirected to attacker-controlled websites. Such redirections can facilitate phishing attacks, credential theft, or delivery of malicious payloads. The vulnerability affects multiple SAP_APPL versions (618, 600-617) and S4CORE versions (102-109), indicating a broad impact across SAP enterprise environments. The CVSS 3.1 score of 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) indicates network attack vector, low attack complexity, no privileges required, but user interaction is necessary. The scope is changed, affecting confidentiality and integrity to a low degree, with no impact on availability. No patches are linked yet, and no known exploits have been reported in the wild as of the publication date. The vulnerability's exploitation could be used as a stepping stone for social engineering or further attacks by redirecting users to malicious sites.
