Vulnerability from github – Published: 2026-07-31 16:44 – Updated: 2026-07-31 16:44

Summary

Spring Data: Unbounded property-path cache keyed by externally-supplied path string

Details

src/main/java/org/springframework/data/mapping/context/PersistentPropertyPathFactory.java:175 · Unbounded Resource Allocation (Algorithmic DoS)

Impact

When a consuming module routes user-supplied dot-paths (sort parameters, projection paths, PATCH paths) through MappingContext.getPersistentPropertyPath(String, Class), each distinct string — including invalid ones — is cached forever. A remote attacker can send millions of requests with unique ?sort=aaaa<n> values and grow the heap until the service OOMs.

Description

PersistentPropertyPathFactory.propertyPaths (line 53) is a ConcurrentHashMap<TypeAndPath, PathResolution> populated by getPotentiallyCachedPath() (line 174-177) via computeIfAbsent. The key is (TypeInformation, rawPathString). Crucially, unresolvable paths are also cached (as PathResolution.unresolved, line 204) so that the same InvalidPersistentPropertyPath can be re-thrown — meaning every distinct garbage string an attacker sends creates a permanent entry. There is no eviction. This is reachable from AbstractMappingContext.getPersistentPropertyPath(String, Class) (AbstractMappingContext.java:345), which Spring Data REST and several store query mappers call with HTTP-request-derived sort/filter property names.

By contrast, the sibling SimplePropertyPath.cache was already hardened to use ConcurrentReferenceHashMap (soft refs); this cache was not given the same treatment.

Exploit scenario

Against a Spring Data REST endpoint, an attacker scripts GET /things?sort=<random-40-char-string> in a loop. Each request fails fast with InvalidPersistentPropertyPath, but each distinct random string leaves behind a TypeAndPath key, a PathResolution object holding the split segments list, and the source string in the map. After ~10M requests the JVM OOMs.

Preconditions

A downstream component (Spring Data REST, a store-specific QueryMapper, or application code) passes externally-supplied strings to MappingContext.getPersistentPropertyPath(String, ...)
No upstream rate-limiting or path-string validation

How to fix

A cache whose key can be derived from external input must be bounded. Replace propertyPaths (line 53) with a ConcurrentLruCache<TypeAndPath, PathResolution> of fixed capacity, or ConcurrentReferenceHashMap (matching the sibling SimplePropertyPath.cache). Additionally, do not cache PathResolution.unresolved results at all (line 204 in createPersistentPropertyPath) — re-computing a failed lookup is cheap, and caching negative results for arbitrary attacker strings is what makes this exploitable.

Adversarial verification

Verdict: TRUE_POSITIVE (confidence: 7/10) — unbounded hard-ref ConcurrentHashMap keyed by raw path string, caches unresolved entries (line 204), reachable via public MappingContext.getPersistentPropertyPath(String, ...); sibling PropertyPath cache was already converted to soft-refs but this one was missed. -3 confidence because the HTTP-input wiring lives in downstream modules (Spring Data REST / store mappers), not verifiable in this repo.

Code at the line — CONFIRMED - Line 53: private final Map<TypeAndPath, PathResolution> propertyPaths = new ConcurrentHashMap<>(); — plain CHM, hard refs, no eviction, no size bound. - Line 175: propertyPaths.computeIfAbsent(TypeAndPath.of(type, propertyPath), ...) — every distinct (type, string) pair is inserted. - Line 204: return PathResolution.unresolved(parts, segment, type, currentPath); — returned from inside computeIfAbsent's mapping function, so unresolvable paths are cached. The PathResolution retains the full attacker string (source = StringUtils.collectionToDelimitedString(parts, "."), line 452).

Callers within spring-data-commons - AbstractMappingContext.getPersistentPropertyPath(String, Class<?>) (line 345) and (String, TypeInformation<?>) (line 350) → persistentPropertyPathFactory.from(type, propertyPath) → straight into the unbounded cache. No validation, no PropertyPath.from gate. - This is the public MappingContext interface (MappingContext.java:174,186), documented to throw InvalidPersistentPropertyPath on bad input — i.e., the contract explicitly anticipates being called with possibly-invalid strings. - No in-repo caller routes HTTP input directly into the String overload. The Sort.Order.property → getPersistentPropertyPath(String, ...) bridge lives in store modules (Spring Data MongoDB QueryMapper, Spring Data REST sort translator). That wiring is out-of-repo as the finding states.

Protections — NONE on this cache Contrast: SimplePropertyPath.java:52 (the PropertyPath.from cache) uses ConcurrentReferenceHashMap (soft refs, GC-evictable). Spring already hardened the sibling cache against exactly this pattern. PersistentPropertyPathFactory.propertyPaths was not given the same treatment.

Stress-test Is this exclusion #3 (intended design)? The PathResolution javadoc (line 426-430) says caching unresolved paths is deliberate — to make repeated lookups of the same bad path cheap. But unbounded hard-ref caching of arbitrary attacker-chosen keys is not the intent; the sibling fix proves Spring considers this a bug class.

  "details": "`src/main/java/org/springframework/data/mapping/context/PersistentPropertyPathFactory.java:175` \u00b7 Unbounded Resource Allocation (Algorithmic DoS)\n\n### Impact\n\nWhen a consuming module routes user-supplied dot-paths (sort parameters, projection paths, PATCH paths) through `MappingContext.getPersistentPropertyPath(String, Class)`, each distinct string \u2014 including invalid ones \u2014 is cached forever. A remote attacker can send millions of requests with unique `?sort=aaaa\u003cn\u003e` values and grow the heap until the service OOMs.\n\n### Description\n\n`PersistentPropertyPathFactory.propertyPaths` (line 53) is a `ConcurrentHashMap\u003cTypeAndPath, PathResolution\u003e` populated by `getPotentiallyCachedPath()` (line 174-177) via `computeIfAbsent`. The key is `(TypeInformation, rawPathString)`. Crucially, unresolvable paths are also cached (as `PathResolution.unresolved`, line 204) so that the same `InvalidPersistentPropertyPath` can be re-thrown \u2014 meaning every distinct garbage string an attacker sends creates a permanent entry. There is no eviction. This is reachable from `AbstractMappingContext.getPersistentPropertyPath(String, Class)` (`AbstractMappingContext.java:345`), which Spring Data REST and several store query mappers call with HTTP-request-derived sort/filter property names.\n\nBy contrast, the sibling `SimplePropertyPath.cache` was already hardened to use `ConcurrentReferenceHashMap` (soft refs); this cache was not given the same treatment.\n\n### Exploit scenario\n\nAgainst a Spring Data REST endpoint, an attacker scripts `GET /things?sort=\u003crandom-40-char-string\u003e` in a loop. Each request fails fast with `InvalidPersistentPropertyPath`, but each distinct random string leaves behind a `TypeAndPath` key, a `PathResolution` object holding the split segments list, and the source string in the map. After ~10M requests the JVM OOMs.\n\n### Preconditions\n\n- A downstream component (Spring Data REST, a store-specific `QueryMapper`, or application code) passes externally-supplied strings to `MappingContext.getPersistentPropertyPath(String, ...)`\n- No upstream rate-limiting or path-string validation\n\n### How to fix\n\nA cache whose key can be derived from external input must be bounded. Replace `propertyPaths` (line 53) with a `ConcurrentLruCache\u003cTypeAndPath, PathResolution\u003e` of fixed capacity, or `ConcurrentReferenceHashMap` (matching the sibling `SimplePropertyPath.cache`). Additionally, do not cache `PathResolution.unresolved` results at all (line 204 in `createPersistentPropertyPath`) \u2014 re-computing a failed lookup is cheap, and caching negative results for arbitrary attacker strings is what makes this exploitable.\n\n### Adversarial verification\n\n**Verdict:** TRUE_POSITIVE (confidence: 7/10) \u2014 unbounded hard-ref `ConcurrentHashMap` keyed by raw path string, caches unresolved entries (line 204), reachable via public `MappingContext.getPersistentPropertyPath(String, ...)`; sibling `PropertyPath` cache was already converted to soft-refs but this one was missed. -3 confidence because the HTTP-input wiring lives in downstream modules (Spring Data REST / store mappers), not verifiable in this repo.\n\n**Code at the line \u2014 CONFIRMED**\n- Line 53: `private final Map\u003cTypeAndPath, PathResolution\u003e propertyPaths = new ConcurrentHashMap\u003c\u003e();` \u2014 plain CHM, hard refs, no eviction, no size bound.\n- Line 175: `propertyPaths.computeIfAbsent(TypeAndPath.of(type, propertyPath), ...)` \u2014 every distinct `(type, string)` pair is inserted.\n- Line 204: `return PathResolution.unresolved(parts, segment, type, currentPath);` \u2014 returned from inside `computeIfAbsent`\u0027s mapping function, so unresolvable paths are cached. The `PathResolution` retains the full attacker string (`source = StringUtils.collectionToDelimitedString(parts, \".\")`, line 452).\n\n**Callers within spring-data-commons**\n- `AbstractMappingContext.getPersistentPropertyPath(String, Class\u003c?\u003e)` (line 345) and `(String, TypeInformation\u003c?\u003e)` (line 350) \u2192 `persistentPropertyPathFactory.from(type, propertyPath)` \u2192 straight into the unbounded cache. No validation, no `PropertyPath.from` gate.\n- This is the public `MappingContext` interface (`MappingContext.java:174,186`), documented to throw `InvalidPersistentPropertyPath` on bad input \u2014 i.e., the contract explicitly anticipates being called with possibly-invalid strings.\n- No in-repo caller routes HTTP input directly into the `String` overload. The `Sort.Order.property` \u2192 `getPersistentPropertyPath(String, ...)` bridge lives in store modules (Spring Data MongoDB `QueryMapper`, Spring Data REST sort translator). That wiring is out-of-repo as the finding states.\n\n**Protections \u2014 NONE on this cache**\nContrast: `SimplePropertyPath.java:52` (the `PropertyPath.from` cache) uses `ConcurrentReferenceHashMap` (soft refs, GC-evictable). Spring already hardened the sibling cache against exactly this pattern. `PersistentPropertyPathFactory.propertyPaths` was not given the same treatment.\n\n**Stress-test**\nIs this exclusion #3 (intended design)? The `PathResolution` javadoc (line 426-430) says caching unresolved paths is deliberate \u2014 to make repeated lookups of the *same* bad path cheap. But unbounded hard-ref caching of *arbitrary attacker-chosen* keys is not the intent; the sibling fix proves Spring considers this a bug class.",
