Details
A vulnerability was found in macropay-solutions Maravel up to 10.73.x and classified as critical. This issue affects the function flush of the component Tagged Cache. The manipulation with an unknown input leads to a authentication replay vulnerability. Using CWE to declare the problem leads to CWE-294. A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes). Impacted is confidentiality, integrity, and availability. The summary by CVE is:
Maravel, a PHP framework oriented towards dependency injection, prior to version 10.74.0 has a high-severity Token Replay Vulnerability arising from a structural lifecycle mismatch between stateless token validation engines and high-performance relational caching layers. Any application with low cache memory that causes premature eviction to free up memory and applications running macropay-solutions/maravel-framework that utilize tymon/jwt-auth for API token authentication and blacklist management or any other package that does the same may be affected. This architectural risk might also impact native Laravel applications utilizing cache tags under specific volatile or eviction-capped environments. tymon/jwt-auth automatically probes for cache tag support. If found, it forcefully wraps 14-day token blacklist entries (jti) inside a relational tymon.jwt tag. In environments where the O(1) Atomic Lazy Eviction model is active — either natively inside Maravel-Framework v20.x or manually backported into v10.x via the explicit DI container singletons provided in PR #104 (App\Cache\TaggedCache and App\Cache\TagSet) — a strict global tracking ceiling (Container::TAGGED_CACHE_TTL_CAP_SECONDS) of 7,200 seconds (2 hours) is enforced to secure the system against memory index bloat. This ceiling forcefully truncates the 14-day blacklist lifespan down to a maximum of 2 hours, after which individual tracking keys naturally expire and disappear from the active cache window. Furthermore, because the optimized engine implements a generational version matrix to achieve O(1) flush speeds, any programmatic or manual invocation of a tag flush or reset (e.g., Cache::tags([...])->flush()) instantly bumps the internal atomic master version pointer. This shifts the computed cryptographic composite hash (sha1($this->tags->getNamespace())) for all overlapping components, rendering the entire existing index immediately unreachable. Consequently, through either natural 2-hour expiration or an intervening tag flush execution (like the cache naturally cleaning old values to free up memory), the invalidation state records are entirely wiped out. Because the tokens' physical cryptographic signatures remain structurally valid for up to 14 days, stolen, hijacked, or legitimately logged-out tokens are instantly and silently resurrected across the entire API gateway, leaving the application critically vulnerable to widespread Token Replay Attacks. Because this issue is caused by an upstream architectural assumption within the tymon/jwt-auth package rather than a core defect inside the framework, there is no direct framework version upgrade that can safely bypass this lifecycle collision without breaking business cache recycling bounds. Maravel version 10.74.0 introduced a way to backport the new fixed tagged cache from 20.x into 10.x by resolving TagSet and TaggedCache from DI, which is how this latent architectural lifecycle vulnerability was discovered. Users must apply the decoupled configuration workaround outlined below. As a workaround, make sure that cache memory size does not generate early natural evictions from cache to free up space, deleting blacklisted jwt ids before they expire. Applications must decouple flat authentication vectors from the relational tagging subsystem. This forces token identifiers to write directly to the primary cache keyspace as flat, un-tagged key-value pairs where they securely retain their unclipped 14-day lifecycle.
It is possible to read the advisory at web.archive.org. The identification of this vulnerability is CVE-2026-55250 since 06/16/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit. The attack technique deployed by this issue is T1040 according to MITRE ATT&CK.
Upgrading to version 10.74.0 eliminates this vulnerability.
