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: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Oct 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 10 Nov 2026.

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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity 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.

What to do

Upgrade wso2am to 4.7.0-r5.

AI-suggested

Upgrade wso2am to version 4.7.0-r5 or later to apply the official fix for this vulnerability. Since a patch is available and the issue is fixed in this version, no additional mitigation steps are required.

Description

A critical security vulnerability in wso2am versions prior to 4.7.0-r5 allows bypass of the max_age authentication-freshness check in the OidcClientCodeRequestFilter due to a timing unit mismatch and incorrect comparison logic. This flaw could enable attackers to circumvent authentication freshness validation, potentially leading to unauthorized access. The issue is fixed in version 4.7.0-r5.

Impact

Exploitation of this vulnerability could allow an attacker to bypass the max_age authentication-freshness check, potentially enabling unauthorized access to protected resources without re-authentication. The impact includes high confidentiality and integrity compromise but does not affect availability. There are no known exploits in the wild at this time.

Summary

The wso2am package contains a vulnerability where the max_age authentication-freshness check in the OidcClientCodeRequestFilter was ineffective because of a mismatch between milliseconds and seconds units and an inverted comparison polarity. This defect means that the intended enforcement of authentication freshness was not operational, allowing potential bypass. The vulnerability is identified as CVE-2026-71575 with a CVSS 3.1 score of 9.1 (critical), indicating network exploitable, no privileges required, no user interaction, and high confidentiality and integrity impact. The issue is resolved in wso2am version 4.7.0-r5.
